Voilà: Francis Gagnon @chezvoila.com · 06/10/2026It’s elections night in Quebec and I celebrate a small victory for Voilà:. After a dataviz training last year, the pie chart of the official results have turned into a bar chart. And in order of performance at that. 📊 0131
Voilà: Francis Gagnon @chezvoila.com · 30/09/2026I just discover that @ourworldindata.org has an interesting section about tourism. 📊 Spain is such a tourism country. And only 48M population. 2 tourists for every local! Explore: ourworldindata.org/grapher/inte... 010
Voilà: Francis Gagnon @chezvoila.com · 29/09/2026Only 7.5% of @datavizsociety.bsky.social are paid members. It's USD 99 / year ($250 for patrons who feel like it). Don't take this association for granted, as it is supported by volunteers and depends entirely on member subscriptions and sponsors. new.datavisualizationsociety.org/membership/ 080
Voilà: Francis Gagnon @chezvoila.com · 29/09/2026Ha! Good catch: it looks nothing like the data presented in the associated paragraph. 110
Voilà: Francis Gagnon @chezvoila.com · 25/09/2026Asked about AI, Prof Saffron O'Neill said that they published a paper based on a study where they asked AI to create visuals for media and none of it was useful.

Voilà: Francis Gagnon @chezvoila.com · 25/09/2026"We were listed as authors of the paper, not designers because our process changed the content." @tomgab.bsky.social 110
Voilà: Francis Gagnon @chezvoila.com · 25/09/2026@tomgab.bsky.social from InfoDesignLab, presenting their work on the concept of overshoot, says that most of the creative process is consultation. People may agree on words, but they all have different mental images. 111
Voilà: Francis Gagnon @chezvoila.com · 25/09/2026@annalombardi.bsky.social from @ecmwf.int says that one reason why this chart became popular is that it broke some of the design rules. 131
Voilà: Francis Gagnon @chezvoila.com · 25/09/2026I missed the visual but Arlene Birt from the IPCC explained that she had the idea (that she calls an artistic project) to add people to charts before making the climate generations version for an IPCC report. 110
Voilà: Francis Gagnon @chezvoila.com · 25/09/2026First time I see the original blanket by Ellie Highwood. Presented by Prof. Saffron O'Neill. What a piece of dataviz history. 📊 111
Voilà: Francis Gagnon @chezvoila.com · 24/09/2026What fresh Adobe hell is this? Even PDFs are trying to become a social media platform. This is all with our best interest at heart, clearly. 001
Voilà: Francis Gagnon @chezvoila.com · 24/09/2026Dataviz question: Since the median is supposed to split the observations in two equal groups, shouldn't we find about the same visual weight above and below the median line in this violin plot? Every single group has more wight above; how can the sum be this low? 140

Voilà: Francis Gagnon @chezvoila.com · 01/09/2026In the great debate on divergent bar charts, we took a side because it made the message stand out. 110
Voilà: Francis Gagnon @chezvoila.com · 01/09/2026Turns out the variation is the message, so we focused on it. 110
Voilà: Francis Gagnon @chezvoila.com · 01/09/2026Some charts were apart from the related text. We brought everything together everywhere. 120

Voilà: Francis Gagnon @chezvoila.com · 01/09/2026It's been a while I've shared one of our projects. A client approached us to give more clarity and punch to their report on downtown Montreal trends. 📊 It was not the first edition, so for once we get to truly compare the before/after impact of our work.

Voilà: Francis Gagnon @chezvoila.com · 20/08/2026I really wish @nber.org would use alt text. It’s a matter of copy pasting. 30 seconds. 000
Voilà: Francis Gagnon @chezvoila.com · 18/08/2026I keep hearing how scientific visualization is conservative because of the journal constraints. But I'm looking at the Nature guidelines for scientific figures and... they're not that bad? 📊 www.nature.com/nature/for-a... 240
Voilà: Francis Gagnon @chezvoila.com · 18/08/2026The resource library with 1,000 entries is certainly comprehensive. datavisualizationsociety.org/resource-lib... 021

Voilà: Francis Gagnon @chezvoila.com · 18/08/2026This new organization by level of expertise is quite interesting, It acts as a filter through a lot of material accumulated over the years. 100
Voilà: Francis Gagnon @chezvoila.com · 18/08/2026They say that the widget on the home page reports on the location of the website visitors, but after 20 minutes and several refreshes, it has not changed, nor registered my visit from Canada. 100
Voilà: Francis Gagnon @chezvoila.com · 18/08/2026The @datavizsociety.bsky.social has a new website. This is no small task, so congratulations to the team. 📊 datavisualizationsociety 1121

Voilà: Francis Gagnon @chezvoila.com · 14/08/2026It resurfaced on X recently thanks for @juanbuis.bsky.social who went viral with it. Ironically, it flopped on Bluesky. I came across it through an X screenshot reposted on Instagram. 110

Voilà: Francis Gagnon @chezvoila.com · 17/07/2026A less controversial way to use a scatterplot than last time. Interesting details 📊 - Use of profile pics - Rotating tooltip (live version) - Use of blue and red for labelling and arrows - Alphanumeric labels for axis - All grey, no black - Y axis only uses even numbers - How they manage an overlap 130
