explore use of tippecanoe for slippy maps

[danlewis85]

Flourish doesn't work well with large vector datasets, such as a full supply of LSOAs for England and Wales, even when the vectors used are highly generalised. The map view presents as laggy and due to generalisation lacks considerable detail at closer zooms.

One approach to address this problem is to 'tile' the data - this effectively means cutting up the vector data into small 'tiles' for different zoom levels and onyl requiring a map to load the tiles it needs at any given time.

This is what tippecanoe does, it is a tiling service that allows you to create vector tiles for use in mapping.

The downside of this solution is that you also need a javascript-driven webmap interface (using leaflet) and a server to serve the map tiles, it's not a single complete solution.
