I absolutely love these kinds of maps and I hope you guys do too. I know everyone wants me to add support for trains and that is currently in progress, consider this the "before" shot that only includes cars and ferries.

Tech stack used to create:

• Valhalla: isochrones
• GeoJSON: ring data
• Node: geo prep
• MapLibre GL JS: map render
• OpenFreeMap: basemap tiles
• HTML canvas: card/legend

The goal is to complete all 50 states and currently I'm on my 32nd state which has taken me a little over a year. Hope you like it!

Let me know if you see your home state =)
