The statistical graph It took a long time or people to make the conceptual leap The Magic Cake Shop from a uantity to an abstract visual representation of that uantity as a line or a bar positioned between several axes Theirst charts were derived rom maps but maps had existed or ive thousand years before charts and graphs appeared in the 1700sBy the 20th century newspapers magazines and #Business And Government Publications All Included Graphics But They Were #and government publications all included graphics but they were done ineptly because they were created by artists not the people who understood the data At the core of the preoccupation with deceptive graphics was the assumption that data graphics were mainly devices or showing the obvious to the ignorant p 53 The book has many egregiously bad examples some of which appeared to be deliberately deceptive such as hiding a business loss by making the y axis start below zero and some just incompetently done apparently by graphics artists who wanted to make a pretty picture without the least understanding of what the data meant Inept graphics also Beauty is a Verb: The New Poetry of Disability flourish because many graphic artists believe that statistics are boring and tedious It thenollows that decorated graphics must pep up animate and all too often exaggerate what evidence there is in the data p 79The book s value comes The Curious World of Wine: Facts, Legends, and Lore About the Drink We Love So Much from theact that Tufte has a number of specific recommendations American Hunger: The Pulitzer Prize-Winning Washington Post Series for how to present data and he cites good examples as well as bad The defining graphic in the book is Charles Joseph Minard s 1861 graph showing theate of Napoleon s army in Russia It is a powerful image telling the dramatic story of an army withering away on the march to and The Mother Zone from Moscow It manages to plot multiple variables on a two dimensional page the size of the army its location in Russia the direction of the army s movement dates of specific events and temperatures along the route of retreat Once seen the graph is unforgettableThere is also another brilliant example a graph by EJ Marey showing train schedulesrom Paris to Lyon in the 1880s At The Void first it looks like a jumble of broken diagonal lines but then it resolves itself The slope of the line indicates the speed of the train the horizontal breaks show where the train is stopped at a station the x axis shows the time of the trip at startinish and points along the way and the y axis the towns the train passes through A great deal of information is packed into a simple easy to read The train schedules put out Amtrak today are The Poke Cookbook: The Freshest Way to Eat Fish far less intuitive and informativeTufte s recommendations boil down one word simplify He coined the word chartjunk and recommends paring everything down to its essentials Hisundamental precepts areFive principles in the theory of data graphics produce substantial changes in graphical design The principles apply to many graphics and yield a series of design options through cycles of graphical revision and editingAbove all else show the dataMaximize the data ink ratioErase non data inkErase redundant data inkRevise and editp 105Somewhere along the way in my career I came to internalize some of Tufte s ideas without knowing I was doing so Whenever I saw a presentation illed with clipart with animated dancing whatevers with unnecessary three dimensional charts and distracting bright colors I concluded that the presenter was either an idiot or unnecessary three dimensional charts and distracting bright colors I concluded that the presenter was either an idiot or actively trying to hide something the viewer wasn t supposed to notice Subseuent events usually proved me rightIf there is one thing that Tufte hates above all else it is the pie chart the only worse design than a pie chart is several of them or then the viewer is asked to compare uantities located in spatial disarray both within and between pies p178 Since they only display a small number of data points anyway you are better off making a simple number chartThis book is worth reading and will make you think about how to best present your information Some of the examples he provides are old including a couple that were certainly created on ancient dot matrix printers but his advice remains excellent For those interested in his additional ideas about graphics presentation he also wrote Envisioning Information 1990 and Visual Explanations Images and uantities Evidence and Narrative 1997.

Of graph pornor us chart junkies as opposed TO CHART JUNK WHICH IS DEFINITELY OUT TUFTE S chart junk which is definitely out Tufte s is Charles Joseph Minard s extremely Sicilian Lives famous infographic of Napoleon s army attempting to invade Russia in 1812 1813 He loves it so much it s reprintedour timesBut there are all sorts of lovely maps and charts Tattoo a Banana: And Other Ways to Turn Anything and Everything Into Art for your graphical delectationDebunking the junk is what Ed is hereor and the pleasure of the text is in the ARID humour he deploys and the way he trusts the reader to be a Alice Oliver fellow smarty pants In of aolks are Smart Way Not An Elitist You And way not an elitist you and are smart way I was laughing When a uoted designer says he s all about conveying the essential spirit of the data Tufte has got me primed Fool NO Show me the DATA not its essence and not its spirit If you work with data if you draw graphics if you look at graphics if you re interested in politics economics geography or science if you like maths art design truth beauty loveread this Edward Tufte is brilliant His books including this one are artwork disguised as a textbook The purpose of all three is to explain both good and bad ways of explaining information but they are so much than that There is a rich history interwoven in the books pages The examples are so interesting that I The Protestant Temperament found myself learning than just how to convey information For example one of the best graphicsor conveying information ever made is a chartmap tracking Napoleon Bonaparte s army s march across Europe which is so impressive it s difficult to describe The graph includes information about army size location and timeline in a very readable straightforwd and yet still beautiful way I was That's So '90s Pop!: A Fill-In Activity Book fortunate enough to attend one of his seminars after I was already aan my work paid The Radiant Child for it and I got to keep the books which delves into all of his texts I highly recommend it because he synthesizes the information beautifully and succinctly and you get all of his books and publications in print If you can t make the seminar no I do not get any kickbacks promise the books are rather complex but they are absolutely stunning and makeascinating reading People have told me to read this book The Best American Crime Writing for years and I ve always been impressed by the strength of their recommendationsHowever on reading this book I was initially underwhelmed Ielt like Tufte was just rehashing common sense about graphs I read through it and The Internet of Us: Knowing More and Understanding Less in the Age of Big Data found myself saying yeah yeah I get it On reflection a week afterinishing I realized this book is genius #TUFTE CONCISELY AND CLEARLY ARTICULATES PRINCIPLES WHICH SHOULD BE #concisely and clearly articulates principles which should be sense so well that they have appearance to be common sense This is a book about graphsHow you ask could anyone write a book about graphs let alone read one Surely you ve never ound the sex appeal of a bar chart the seductiveness of a scatterplot Well my riend you simply have never realized the power of a well designed graph Tufte took on the challenge of making visual information interesting decades ago and it s still considered one of the top 100 books of the 20th century He shows examples of what the best displays and worst displays are in the Tempting Eden first part of the book In the second he breaks down graphs piece by piece as the reader learns how to construct a useful and informative graph chart table or whathaveyou The best graphs etc aren tlashy You don t need any Talking to Dragons (Enchanted Forest Chronicles, fancy computers to make them inact Tufte particularly disdains computer programs or making everything busy and excessive As is true of Although originally published in 1983 when professional graphics artists prepared most of the charts and graphs used in presentations and official publications this book remains useful or anyone who wishes to convey information clearly and concisely I can remember a job early in my career when all presentations had to be approved by two levels of management then submitted to the graphics shop at least a week before they were to be used and what came back was an inter office envelope ull of transparencies to be shown on an overhead projector We have come a long way since then but powerful graphics software has not necessarily improved our ability to get the message across in an understandable and informative wayTufte starts with some history of.

When I started secondary school I was mildly apprehensive about Physics An Unfamiliar Word That Elicited An Actual Shudder From an unfamiliar word that elicited an actual shudder The Drowning Man from mother Fortunately my elderly teacher had an infectious affectionor his subject I remember that he noticed me examining the monthly night sky chart pinned to the classroom door and thereafter would print off an extra copy specially and wordlessly hand it to me if he saw me the corridor never in class not wishing to embarrass Our irst lessons tried to tell us what the subject was all about and a poetic but
article telling me that it about among other things not being able to push a blade of grass into the trunk of an oak tree demonstrated clearly that some things are better learned by seeing and doing than by readinghe needn t have worried evidence of my geekiness was not in short supplyOne of our early experiments was The One With The Pendulum turns out that in the UK this is an A level practical I guess in those days secondary school wasn t all OMG exam in 5 years PANIC and our homework was to write it up When I had inished it I must have shown my Dad as he asked why there was no graph We weren t told to draw a graph I replied But graphs are wonderful he said Let s draw one anyway and he showed me how Our graph which is probably still in my parents attic somewhere plotted length of pendulum against swing time which unfortunately yields an exponential curve that s hard to work with You can when you do the experiment at A level linearise the graph s euation by plotting the suare of the time period and then the gradient tells us little g the strength of the Earth s gravitational GREAT INVESTMENT, THE field Neat ehI have taught scienceor a ew years now and I could not have ailed to notice that many kids hate graphs and graph drawing It is unuestionably hard work and needs an understanding of numbers and design logic I m lucky that I got an undeserved merit The Lively Art of Writing for drawing an unsolicited graph in myirst month of high school because since that day I ve been totally reaky or a nice chart these two pictures are rom my own lab book not the text This review is dedicated to my Dad Tufte really loves data This book has an informative accurate but kinda DRY title I would have called itSHOW US THE DATAuhhhh uhhhh I ve made a mistake Tufte says thinking data is boring leads to bad lying graphs If your data is boring why are you even presenting it He is crisply derisive of the idea that data needs graphically sexing up to be understood As Freire tells usTRUST YOUR AUDIENCETufte bemoans that graphs are designed and drawn by olks trained as artists rather than The Glass Ocean folks trained in the relevant mathematics Graphical competence demands three uite different skills the substantive statistical and artistic Allowing artist illustrators to control the design and content of statistical graphics is almost like allowing typographers to control the content style and editing of prose Don t decorate the data REVEAL ITBad graphics also lack integrity Intead of SHOWING THE DATA they distort it usuallyor some political end There are LOTS of examplesAnd here is a modern example I couldn t resist adding XDHowever the concern with graphical integrity has often not helped It tends to encourage the general dislike of graphs and the tendency or publications to dumb them down Tufte points out that while graphical sophistication is usually low in news publications journals and text books the text sophistication is high sometimes reuiring expert knowledgeMany data sets are better presented in a well organised table than in a drawing Tufte ollows this principle in presenting data on graphical sophistication and data density and in showing his commissioned designs One super table is ar better than a hundred little bar chartsOh and or the love of all that is good The Leadership Gap: What Gets Between You and Your Greatness follow da Vinci and put the damn chart next to the text or better nested cosily inside None of this seeig 2 Tufte radically redesigns the histogram and the scatter plot to remove distractions and non data ink moving towards clarity data density and design grace I won t spoil As or the pie keep it in the kitchen and put pumpkin in it pie charts should never be used There is plenty.
