Data Lens Developer's Guide

Creating Visualizations

You create data visualizations using the Data Lens JavaScript API. This library is a module of HERE Maps API. It connects with the Data Lens REST API and provides data-driven styling of data on a map.

Figure 1. Data Lens JavaScript API

The main features of the Data Lens JavaScript API are the following:

  • Data Lens REST API connector (Service) for HERE Maps API
  • Markers, clusters and primitives with styling parameterized by data and zoom level (data-driven styling)
  • Geometric features with styling parameterized by data, zoom level and the interactive state (data-driven styling)
  • Value-based heat map with density alpha mask

For the full JavaScript API reference, see JavaScript API.
