How are we going to describe our world? • Are abstractions e.g. Histogram buckets • Work on multiple dimensions Visual, cognitive, emotional, analytical @undrstndng

- 25. Clear Can someone describe what your chart is trying to do in 2 sentences using simple words? Better yet, can two people look at the chart and give the same basic explanation? Pick a model based on your information, not vice-versa. @undrstndng

- 28. Let’s look at those examples again: Worldwide Nuclear Weapons Detonations A Real-Time Map of Births and Deaths @undrstndng
- 29. Ethical While designing the chart, write down what you are leaving out and review it. Identify what narrative you are trying to tell and determine if what you are leaving out undermines that narrative. If a story is too complex to tell in a chart, it may not be true. Change scale, proportions, etc on the chart to identify possible distortions of the visual data. @undrstndng

Credible A lot of this is an outcome of doing other things right, but there are some things you can do make sure you don’t lose credibility: • Aesthetic decisions • Citations • Proper professional and cultural vernacular for audience (e.g. physicists vs. engineers, dollar vs. euro, children vs. adults) @undrstndng

- Welcome to our talk, Listening to Data. We’re very happy to be part of an event like A2 Data Drive – and talking about such a great topic. Today we will be discussing how to make better visualizations by focusing on being conversation based and data driven.
- Hello, my name is Kaarin Hoff – I’m an information architect, or IA for short, at TUG. My background is also quite varied – but visualizations and UM have remained consistent. In undergrad I studied History and Art History, spending a lot of time in archives piecing together information from images and text to get as clear a story as possible. After that, I worked at UM planning orientations from end-to-end -> promotion, registration, ect. That is when I really began to understand the how crucial visualizations are to our everyday life. So many of my meets were disasters – getting so far off track bc a column’s sum wasn’t correct or a website’s purpose wasn’t agreed on because the whole meeting was spent discussing how an image wasn’t aligned correctly. One day someone told me the IA of the site I managed was bad. So I Google “IA” – and shortly there after I applied to grad school bc it sounded so cool that’s what I wanted to do all the time! So I when to SI where I met Dan Klyn by taking his IA course and now I work at his company making useful things out of information and loving it.

- Everyone here has a different story of how they came to be in this room with their current data need – but the great news is we’ve ALL been working with visualizations our whole lives. Who here has made a bar chart? Knows that a pie chart has nothing to do with Pillsbury dough? Exactly. So whether you know 2 charts or 50 charts, the principles we’re talking about here today applyBecause we live in a world full of data questions. We have all this information and now we need to figure out what to do with it. Visualizations are a tool for putting that data to work for you – in convincing your stakeholders, in explaining the problem, even in suggesting solutions.
- The purpose of today’s talk is to provide a core set of principles that transcends best practices. There are no shortage of examples of good and bad visualizations. The trick is choosing the BEST way to visualize your data – so let’s discuss that principles that will allow you to get there.Before we dive in let’s look at some visualizations to think about what they have in common and what they can accomplish
- This visualization was made by Minard in 1869. It is the aspirational, unachievable, Mona Lisa of visualizations. Analyzing the best of the best, something that is still regarded as the best 130+ years later can show us some of the core principles of visualizations. Tufte analyzed this visualization in his book, Beautiful Evidence. Documented
- Tufte analyzed this visualization in his book, Beautiful Evidence.
- Answer the question: Compared to what?That’s 1 out of 42 survival rate
- Show explanationWarmest day was 32 degreesMinard doesn’t say “the cold killed them” – but the evidence being presented together like this declares the relation. We humans make associations when things are placed next to each other like this. Minard used this wisely, since he had many legitimate first- hand accounts of soldiers freezing to death.
- 6 variables here : size of army, geographical location, direction of movement (invading & retreating), temperature, timeIf you evidence is numerical and geographical, that’s ok. Combine them to tell the story. Don’t be feel limited to a certain type of visualization, like a line chart, and miss out on telling your whole story. Be true to your data
- Visual can be deep to add evidence – text, images Make your main point right away, but you can give you audience more to digest in they lingerLike a painting…
- Minard’s visualization has stood the test of time and is so revered because of the rigorous documentation attached to it. Everything is proved that he represents here. So no you don’t need to go to the library archives, but do include or refer to where your data is from. Do include a ledged if necessary.
- Minard was a soldier telling soldier stories, exposing the cost of war. Tufte said it best so I’ll read this “That the word ‘Napoleon’ does not appear on the map of Napoleon’s march indicates here at least full attention is to be given to memorializing the dead soldiers rather than celebrating the surviving celebrity.”
- subway - Rhetoric - Sequence trumps location Abstraction - location eliminated Multi-D punch - yin/yang, the power of a loop or line
- What the system would look like with geography…
- Army - Rhetoric - War is suffering? don’t invade Russia? Abstraction - Described in the narrative Multi-D punch - Temperature, location, time, death
- Bell curve - Rhetoric - THIS IS HOW THE WORLD WORKS Abstraction - sample size, histogram bucket size, “p<.05” Multi-D punch - pattern matching, storytelling, profiling----- Meeting Notes (11/8/13 14:00) -----Don't mention histogram
- ----- Meeting Notes (11/8/13 14:00) -----We've looked at some reasons that visualiztions work and we've described the common DNA of visualizations.
- Visualizations as conversation centerpiece - sometimes with people in the room, sometimes with people you will never see - must consider your data, your goal, your audience to pick the right visualizationClearUsefulEthicalCredible
- Pick a model based on your information, not viceversaCan someone describe what your chart is trying to do in about two sentences using simple words.Better yet, can two people look at the chart and give the same basic explanation.
