#30DayChartChallenge Day 16 : Causation

#AngineDePoitrine has been around since at least 2024 but they broke the internet in the last few months 🔺

The search term 'angine de poitrine' exploded in Google pretty much when their live performance video was posted on YouTube (Feb 4) 🎸🎸🥁

#Rstats

I also did the analysis with the other main parties of course. Note the negative correlation for QS (which was somewhat expected)

In short : yes, fairly. See caption. Slightly more than with age and statistically highly significant. Most of the couple of outliers bottom-right are ridings that have been supporting the same party since forever, hence the annotation.

#30DayChartChallenge Day 15 : Correlation

A mere curiosity I had regarding the last general election in #Québec in 2022 : was there a positive association between support for the incumbent party (CAQ) and the number of homeowners, per riding? 🏠

#30DayChartChallenge Day 14 : Trade

RAM price drop? 😱

Recent spot price data for RAM chips and sticks shows a slight decline over the past few weeks

Not exactly a freefall but these are still the first drops since it went bananas starting last fall

(These aren't retail prices)

So #Yukon has the largest number of protected areas relative to its size. Well, now I know, and so do you.

At 4 %, the lowest nation-wide, #PrinceEdwardIsland probably doesn't have a lot of land to spare. Potatoes need space 🥔

#30DayChartChallenge Day 11 : Physical

So, have you been skipping leg day? 🧐

Actually I suspect you've been skipping calves nearly half the time, as well as abs, and, yes, maybe some legs too, according to data by #Boostcamp as shown in this chart

#30DayChartChallenge Day 9 : Wealth

Simple comparison of...

▶️ GDP per capita (measure of wealth in a county, though criticized)
vs.
▶️ Gini coefficient (measure of income inequality)

#30DayChartChallenge Day 8 : Circular 🎡

It looks like some months have been warming more than others in #QuebecCity in the last ~30y, like December and January, while it's not as strong for summer months but they are still warming more than anything 😐🌡️🔥

Not sure how relevant this information is in the games, at least the few that I've played, but I was curious anyway. I believe high weight and height usually comes with higher HP and defense, but that would be for a separate analysis, assuming that this hasn't already been done several times

It really helped that all Approval lines decreased and Disapproval lines ones increased, otherwise the positioning of the percentages labels on the right would have been more difficult across plots

Multiple slope charts showing mostly decreased net approval ratings for President Trump since the start of his second term, as polled to Americans by YouGov on January 28th, 2025 vs. March 30, 2026. Socio-demographic group include registered voters, female, male, republican, independent, democrat, under 30, 30-45, 45-65, 65+, high school or less, some college, college grad, postgrad, white, black, hispanic, other race. The sharpest inclines in disapproval, and vice versa steepest decreases in support, are found among independents, under 30 and 30-45, college grads, blacks, hispanics, and other races.

I deleted a previous version of this post because of a common issue with the #PolarChart : except for that frog in the center, all categories "lacked" exactly 1 observation.

That's because the 1st and last observation of each category on x-axis were both at the same place, so it looked like 1 ob 🤷

Emoji breakdown of threatened species

🐸 1 Amphibian
🦎 6 Reptiles
🦊 18 Mammals
🐌 21 Molluscs
🌿 21 Plants
⭐ 25 Other Inverts
🐦 30 Birds
🍄 38 Fungi
🐟 52 Fishes

This chart shows how many species are considered threatened in #Canada, broken down by major taxonomic group (mammals, birds, amphibians, plants, etc.), according to the IUCN Red List. Title : How many species are threatened in Canada? Subtitle : The count in each major taxonomic group, according to the Red List. The entire image has a red background with everything else in white (text, labels, data points etc). The chart is a circular pictorial plot, using aspecific pictogram for each taxonomic group. There's Amphibians, Reptiles, Mammals, Molluscs, Plants, Fungi, Birds, Other Inverts, Fishes. At the center there is a frog, representing the Amphibians, it's alone as there is only one species of Amphibian that is threatened. It then extends to 5 pictograms for reptiles and then goes all the way to fishes which are the largest group in terms of threatened species, for a count of 52 species. The source is The IUCN Red List of Threatened Species Made by @stevecarufel.bsky.social for the #30DayChartChallenge

Gigantic blaze in the #Etosha National Park and around in #Namibia as seen from above

Burnt area was estimated at nearly 1M hectares 2 days ago. That's more than all the fires in British Columbia this year 😳

Fortunately, it didn't grow much since then and appears to be contained

This dark mode charts shows the average US retail gas and diesel price per gallon in US Dollars from 1995 to 2025 (June). There are two square charts one after the other. On the left, in the background in transparent colors (yellow, orange, red) we see the full weekly data broken down by grade for gasoline and full color trend lines for each grade : regular, midgrade, premium. On the right, same idea but for diesel only and in purple, all grades included, not broken down. We see that, since the 2010s, the 3 grades of gasoline naturally had some slight differences in their price but the differences widened since 2010 and even more so since the mid/late-2010. In all cases, the general pattern is somewhat linear from 1995 to 2010 and then stays flat until the late 2010s. Since 2020, its been going up steadily. Data is from the U.S. Energy Information Administration as cleaned and curated for #TidyTuesday by Jon Harmon.

So it's #TidyTuesday and we're looking at US retail #gasoline and #diesel prices of the last 30 years
