Built with @Mapbox, @vite_js, @reactjs, @fontawesome, @tailwindcss. Data processing with @turfjs, and R (gtfsrouter package). Deployed on @Netlify. Code on @github.
Inspired by the rapid-fire experience of https://t.co/hrHmjUax3R, I built a similar interactive that shows how far you can get from each NYC subway station in 40 minutes. Have a look at https://t.co/uxsEH5arc3 ๐

I love how easy it is to use JS libraries with @FableCompiler To use @turfjs I just need to specify which functions I need and what types I do expect #fsharp

10-20-30-40 minute isochrones for subway + walking(ish) from Atlantic Ave/Barclays Center. This is a @turfjs -intensive workflow, using buffer, dissolve, truncate, and intersect. Now to make them for the other 471 stations. cc/ @_benjamintd

After a bit of work the Turf.js docs should now be responsive and be an all round nicer experience on mobile/tablet than they were before!

This Pi Day, don't worry about using pi to calculate area - use Mapbox GL JS and @turfjs! This example from our Docs shows how to calculate the area of any mapped polygon. See it in action: https://t.co/eXX7QIty3l

A "new" way to find locations on a map, powered by @Mapbox & @turfjs. Search for a geolocation, change the center marker & drag to resize the radius zone. Pairs with @thatsfinsweet Attributes to update a filterable list. Coming soon!

Make your web maps look more like print โ by overlapping a hidden symbol layer along a map edge you can avoid labels being clipped with @Mapbox and @turfjs. Play with it here: https://t.co/jF4enVbkFj

Thanks to @willy_maps idea and code, and a bit of help from @en_dash, I have now made a totally essential spidermap of trig pillars across Great Britain - shows the 8 closest trig pillars to the centre of the screen https://t.co/jWpRnTUJgL

Another day, another #dataviz. This time, Joy Division-style ridgeline map with altitudes on @observablehq with the help of d3 and @turfjs. #observable #datavisualization

Thanks to @turfjs for a powerful spatial analysis toolbox to enable this project.
I have open sourced code used to calculate walk potential for cities. Some assembly required. https://t.co/ixEG7K6GMa Here's an example use contrasting walk potential (green) with missing sidewalks (red). @samth
