GitHub Page and Live Demo



Simple page

For a simple view of your taxonomy chart, you can use our demo on github. Here is the link and what it should look like :<your-style-url>

Without style url in the query parameter, it will show our simple example.

Web integration

You can add your taxonomy chart in your website or blog by using this code in your HTML :

  <link rel="stylesheet" type="text/css" href="">

  <taxonomy style-url="<your-style-url>"></taxonomy>
  <script src=""></script>

  • taxonomy:group: This must match a from your global metadata. Required.
  • taxonomy:casing: This will refer to another layer id. That's mean the current layer is the casing of the layer pointed by taxonomy:casing. This layer must be a line type. This will render an outline for taxonomy:casing (We can also use ref id from your layer).
