To run the demo, first download the public domain natural earth surface relief tiles from one of these sources:

• ipfs get -o ne2srw /ipfs/QmV5PLazMsBk8bRhRAyDhNuJt9N19cjayUSDvw8DKxSmFz
• dat clone dat://db9c54fd4775da34109c9afd366cac5d3dff26c6a3902fc9c9c454193b543cbb ne2srw
• https://ipfs.io/ipfs/QmV5PLazMsBk8bRhRAyDhNuJt9N19cjayUSDvw8DKxSmFz
• https://ne2srw-tiles-substack.hashbase.io/

Copy (or make a symlink) of that ne2srw directory into example/tiles so that example/tiles/tiles.json exists.

Now you can do npm run dev to run a dev server with the example code in example/main.js.
