VisQuill Lens
A complete, browser-based tool for exploring geographic data — built entirely on the VisQuill GDK. Drag interactive lens overlays across a map; each lens aggregates the data beneath it into a live bar chart. It's one example of what the toolkit can build when taken all the way to a finished product.

Power BI custom visual
The same lens visualization is available as a Power BI custom visual. Evaluation builds are provided on request.

Built with the GDK
Lens is one thing the GDK makes possible
Reactive geometry, constraints, interaction, and SVG rendering — the same foundation Lens is built on is available to build your own interactive visualizations.
