This is a niche post, but tippecanoe + PMTiles + MapLibre is a remarkable technology stack Visualize tens of millions of features on a map, lightning fast, all with free and open source tools running locally on your computer

A benefit to dogfooding in FOSS development? If I need a new feature, I just implement it. I use {mapgl} across all my projects; recently I needed an easy way to format numbers in popups. The result: a new number formatter in the package, which is now yours to try! #rstats

Tutorial: fundamentals of map design with the {mapgl} #rstats package. Learn how to use continuous & categorical color schemes, set up custom legends, format pop-ups and hover effects, and much more. Read the vignette: walker-data.com/mapgl/articles…

Saw a post from Andrej Karpathy about the value of "Cursor for slides". I asked Anthropic's Claude Code to read one of my blog posts (walker-data.com/posts/overture…) and convert it into a Quarto slide deck. Three prompts later... it did pretty well! "Vibe-slide-decking", perhaps?

AI just got a sense of place. 🌎 We just launched Mapbox MCP — the first protocol that makes LLMs and agents spatially aware. Let’s talk about why that matters 👇

What is your favorite function in R❓ Wrong answers only.

lenght()

Working with Claude Code as a pair programmer has taught me something: I like creating more than I like coding. Previously, coding was a requirement for creation (GUI tools only get you so far). Now, I can focus on design and architecture while Claude handles the mechanics.

Came across this while working with some Census data - Census tracts directly on Florida's coast overwhelmingly have a median age of 50 or higher. Florida beaches as retirement destination is no surprise, but patterns like this really pop out when you map them interactively.

The new `mapboxgl_view()` and `maplibre_view()` functions in #rstats's mapgl package return full-fledged map objects, so you can add features to your maps while saving time. Example: spin up a choropleth with a geocoder to help you explore the results with hardly any code.
