Simple static page that draws a straight line between two coordinates using Leaflet + OpenStreetMap.

• index.html — The map page. Open it and pass URL query parameters:

  ?lat1=40.2616&lon1=-76.969653&lat2=33.016416&lon2=-84.165564
  

1. Create a new public repository on GitHub (name it map-line or whatever you like).
2. Upload index.html and README.md to the repository root.
3. In the repository settings → Pages, set the source branch to main (or master) and folder to / (root).
4. Wait a minute. Your site will be available at:

   https://<your-username>.github.io/<repo-name>/
   

Call it like:

https://<your-username>.github.io/<repo-name>/?lat1=40.2616&lon1=-76.969653&lat2=33.016416&lon2=-84.165564
