Graphiques Dégénérés: An Exhibition of Datavis Failures
Data visualization is the art of turning data into meaningful graphics. But sometimes, this process doesn’t go as planned. When it fails in style, the results can be surprisingly beautiful. I come from an art background, so I asked myself the question: can we present datavis failures in an art gallery and treat it as a form of Glitch art? That’s what we did. And it was fun.
A common language for product specifications
A complete product development flow involves multiple people in interaction. Each stage of the process can sync-up by sharing specific deliverables. Typically, product managers will write down a set of user stories and feature lists, Designers will turn them into wireframes and flow diagrams, project managers will break the features down into tasks, etc. It can be hard to translate these documents across the pipeline. What if we could find a common language, so everybody can collaborate on building a shared vision of the product?

Modding a 18$ Tube Screamer clone
The Tube Screamer (TS) is an excellent overdrive platform for modding. Some versions of it like that one are still in production. There's a cult around the TS and when you look at modern overdrive and distortion schematics, you will see that a lot of them are mostly glorified TS mods. If you want to get started modding pedals, instead of destroying a 250$ pedal this 18$ CAD clone is very close to the original. In my case, I changed the range of the drive and tone, added more bass and replaced the useless switch to toggle clipping diodes instead, which completely change the drive structure.

VisMTL #9 et #10
VisMTL9
Le meetup VisMontreal #9 portait sur l’écosystème de la datavis, rapportant les dernières nouvelles de l’industrie, les studios, les outils, les tendances, les conférences, etc. Le premier invité était Ian Johnson, en direct de San Francisco. Ensuite je donnais des nouvelles de l'industries, suivi de Jean-Hugues Roy qui nous parlait de l'état du journalisme informatique au Québec.https://medium.com/@christopheviau/vismtl9-des-nouvelles-de-lindustrie-ef47608d3669
VisMTL10
Le meetup VisMontreal #10 a profité du passage de conférenciers de réputation internationale qui étaient à Montréal pour présenter leur recherche à CHI, une des plus importantes conférences en datavis et Interaction Humain-Machine.https://medium.com/@christopheviau/vismtl10-la-recherche-a018e4cb64ee

Pour ma part, je présentais différents types de graphiques tirés d'une galerie de 12000 exemples de visualisations. Le but était de montrer que certains graphiques se ressemblent mais sont en fait fondamentalement différents et surtout que certains graphiques différents sont en fait équivalents.
Voici les diapos utilisées ainsi que quelques liens vers des visualisations méconnues mentionnées durant la présentation.

Planet OS Exchange
I learned a lot about maps visualization and sensor data. Here is an early prototype.
That's where I developed Cirrus.js. Most data we currently have is raster data, but there's always the occasional time series.
And temporal coverage chart.
But most of the visualization work is on map polygons and raster data. Here is for example a screenshot of the colour palette dropdown.

Hackathon Québec Ouvert
We won a prize in the Hackathon Québec Ouvert with an application for mapping your own constellations with the Québec Open Data. I worked as part of the Chambre Blanche team with Nataliya Petkova, Jeanne-Landry-Belleau and Pierre-Luc Lapointe. More details coming soon.
Developing a D3.js Edge
I co-authored a D3.js book with Andrew Thornton, Ger Hobbelt, Roland Dunn and Troy Mott. It was a book sprint: writing the core of it over 2 week-ends. We focused on how to write production D3.js code with the reusable API. The e-book is available on Bleeding Edge Press and on Amazon.

Getting involved with the D3 community

I gave a talk about getting involved with the D3 community at Trulia for the Bay Area D3 User Group, with Scott Murray and short talks by Jérôme Cukier, Santiago Ortiz, Jyri Tuulos, Alex Johnson, Amelia Greenhall, Mike Travers and Péter Boda. My slides are here and it was recorded on video. I launched my alternative D3 gallery made with D3 and based on a Google Spreadsheet.
Here is the talk in a blog post format. It is mostly a collection of links for getting started with D3 and contributing to this awesome community.
