#hackaviz2020
March 2020 (Organized with Toulouse-Dataviz)
The third edition of our annual Data Visualization context has been a real success, despite the covid-19. We decided to maintain the contest, and 37 contributions were submitted. You’ll find here all the dataviz. The event (as well as the jury) was online only and we celebrated the winner in a live Twitch broadcast gathering more than 100 viewers and recorded.
How to Lie with Graphics
October 2019-Feb 2020 ( MIAT Toulouse; ENS Lyon & SMART-LERECO, Rennes)
A new (improved?) version on this really hot topic, still with 10+ rules for lying and a little bit more of structure in the presentation. I was really happy to learn even more on truncated and double axes for these seminars. Thank you all for the invitation and for the great audience. The slides of my MIAT presentation are available here,those for my ENS-Lyon seminar are there,and those for my seminar at SMART-LERECO (INRAE, Rennes) are there

Axes of evil: How to lie with graphs

Um blog com exemplos e links para outros sites.
As Mark Twain once said, “Never let the truth get in the way of a good story.” Here are a few techniques to hide those pesky numbers and tell the story you feel, not the one you can prove.
Don your handlebar mustache and practice your evil laugh — we’re going in.
The Beautiful Hidden Logic of Cities

Padrões identificados em mapas de cidades.
After finishing my map of the most common road suffixes by length, I realized I could also map each individual road, colored by its suffix. This has led to the loveliest maps I’ve made.
Driving around your city, you’re probably somewhat aware of Avenues and Boulevards and Streets and Roads and so on. Here in Portland, at least, I know that Avenues run north-south and Streets run east-west. However, it’s hard to get an overall view of how all these road designations knit together. By coloring them, we can suddenly see a new, stunning view of what we normally take for granted.

RateBeer puts out a list every year for top 100 breweries in the world. The rankings are based on reviews, range across styles, and historical performance (and maybe a bit of subjectivity). RateBeer just published the list for 2018. Here’s a map of the 73 U.S.-based breweries.

Now that we know where they are, let’s find out how to visit all of them in one go.

Basketball Stat Cherry Picking
Posted by Armando Brito Mendes | Filed under estatística, visualização

Deep into the NBA playoffs, we are graced with stats-o-plenty before, during, and after every game. Some of the numbers are informative. Most of them are randomly used to illustrate a commentator’s point.
One of the most common stats is the conditional that says something like, “When player X scores at least Y points, the team wins 90 percent of their games.” It implies a cause-and-effect relationship.
The Cleveland Cavaliers won the most games when LeBron James scored 30 or more points. So James should just score that many points every time. Easy. I should be a coach.
It’s a bit of stat cherry picking, trying to find something in common among games won. So to make things easier, and for you to wow your friends during the games, I compiled winning percentages for several stats during the 2017-18 regular season. Select among the star players still in the playoffs.

50 Great Examples of Data Visualization
Posted by Armando Brito Mendes | Filed under visualização
Bons exemplos de representações gráficas
Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information.
And trying to find related content can also be difficult, depending on what data you’re looking for.
But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner.
Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter.

This website allows you to explore vector fields in real time.
“Vector field” is just a fancy way of saying that each point on a screen has some vector associated with it. This vector could mean anything, but for our purposes we consider it to be a velocity vector.
Now that we have velocity vectors at every single point, let’s drop thousands of small particles and see how they move. Resulting visualization could be used by scientist to study vector fields, or by artist to get inspiration!

Stay tuned for updates on Twitter.

Pianogram
This is what you get when you cross a histogram and piano keys to show note distribution of songs. It’s the pianogram. View examples such as Fur Elise or the classic Chopsticks, or punch in your own MIDI-formatted song for a taste of the distribution ivories.
Here’s the distribution for Kenny Loggins’ Danger Zone.
Because why not.
