#toronto #cycling #data
Two side-by-side charts showing travel times on the 510 Spadina between Sussex and Lake Shore Blvd., comparing October 2025 to March 2026. Overall the charts show that median travel time decreasing by about 1 minute, with variations by day of the month.
recently charting travel times along 510 Spadina, comparing October 2025 to March 2026 ---
(the ~1min improvements approx. align with City's findings on impact of enhanced transit signal priority at king, dundas, and college)

legibility on these is limited a bit by how smaller values can get hidden behind larger values -- but i was mostly interested in broader trends and had fun playing with the overall visual style (ggplot + gimp)
Oblique 3d bar chart showing number of bike share trips in toronto per hour from march 11 2026 to april 3 2026. Weekdays show bi-modal distributions, weekends do not.

#toronto #cycling #data #ggplot2
12 month calendar arranged in a 3x4 grid where each day is coloured by the number of bike share trips --- unsurprisingly, there are many more trips in warmer months
recently made this little calendar (2025) to look at patterns in bike share toronto ridership

A language map of Montreal by @jamaps.bsky.social which inspired a language map of NYC by me.
These and much more in this week's (free) newsletter. www.howtoreadthisch.art/visualizatio...
third being population density via dot size, but I ya bi-variate just for colour
Map of Montreal and the surrounding region using a grid of dots to visualize the % of the population that can speak French and English via different colours. Size of dots indicate population density.

#montreal #maps #languages #geography
Map of the Greater Toronto Area covered with squares arranged in a 1km grid spacing. The colour of the squares indicate the % of people that speak Arabic. The size of the squares is the total population. The map shows that there are relatively more Arabic speakers in northern and western Mississauga, northern Oakville, Milton, and northwestern Scarborough.

#toronto #maps #housing
Map of the Greater Toronto Area covered with dots arranged in a 1km grid spacing. The colour of the dots indicate % of people that speak Spanish. The size of the dot is the total population. The map shows that there are relatively more Spanish speakers in the west and north-west of Toronto and in some outer municipalities like Bradford, Oakville, and Brampton.
Made a quick map of knowledge of Spanish in/around Toronto --
(This was a bit of an experiment - testing out a process of interpolating census data to a bivariate dot grid)

Side-by-side cropped screenshots of a 1993 Toronto transit map: Left is showing central Toronto, right is showing the map legend
always fun to look at old TTC maps like this one from 93 --- when the Harbourfront LRT had a bold line / rapid transit branding shortly after it opened

very cool! are you deriving speed estimates from arrival predictions data?

Series of stacked maps showing how the new Eglinton Line 5 transit routes relates to building footprints; space devoted to cars, bikes, and pedestrians; zoning; green space; population density; household income; and senior populations.

big fan of #tippecanoe -> #pmtiles -> #maplibre -> #github pages workflow, can pretty easily take a ~300mb .shp like this and viz it in-browser (no fancy db, server, or saas hosting)

Multivariate map of Canada showing environmental vulnerabilities – biodiversity loss, water stress, soil degradation, and deforestation – alongside accumulated climate events from the past several years – including floods, wildfires, long-term sea level rise, and droughts. The map combines these eight impacts via small pie charts, that when combined represent the intensity of climate-change risks.
