#leafpad

Leafpad is a simple way of viewing csv files that contain geojson columns.

#How it works

1. Start a local web server
2. Put a csv file into the data directory (demo.csv is there by default)
3. Open a browser to http://localhost:3000/show/csv/demo (where "demo" is the base filename)
4. Columns whose names end in _geojson will be displayed as geojsons
5. Columns named "lat" or "lon" (or latitude or longitude) will be markers
6. That's it!

But wait, there's more!

• click on geojson columns in the csv to fly there on the map
• put multiple csv files into a directory, and view them all at once
• use the mouse to scroll/pan
• type "l" to generate a link with the current zoom and lat/lon
• okay, that's really it
