The easiest way is to create your own map tiles based on that data. There are a couple of ways of achieving this but my suggestion is that you use TileMill. It's free and very easy to use. So, basically you would:

• Configure how the map should be displayed (like the color of the polygons) with a special CSS-like language inside TileMill

• Generate the tiles

• Load a new TileLayer in your Leaflet map that references your files
