Example Usage

For example, to draw a grid map of the US, create a grid map component and pass gridmap-layout-usa as the layout. View source of this demo for example.

var chart = new d3KitGridmap('#usa', {
  col: function(d){return d.x;},
  row: function(d){return d.y;},
  fill: function(d){return color(d.name.length);}
})
  .data(gridmapLayoutUsa)
  .resizeToFitMap();

For more detailed usage please refer to the API Reference.

Layout

d3Kit-gridmap does not come with layout, which is an Array of tiles and their positions, which make it can be reused for a map of any region or country.

The layout has to be passed to the chart by calling chart.data(layout) for this component to show something on the screen.

In the simplest way, you can just pass a custom Array as your own layout.

chart.data([
  {key: 'region1', col: 1, row 2},
  {key: 'region2', col: 1, row 3},
  ...
]);

Or use these available layouts:
