Understanding the Voronoi Diagram
Explore how Voronoi diagrams help enhance interactivity in scatterplots by enabling tooltips to appear when users hover near data points, solving common overlap and precision issues. Understand their application through practical examples and how D3's built-in Delaunay library automates their creation for responsive visualizations.
We'll cover the following...
We are going to spend some time improving the tooltip we developed in the past few lectures. Right now it is annoying to hover over a dot. We have to place our mouse directly over the very small dots, and some dots overlap with one another. We have to be very precise with where we point our mouse. Some of our readers may have difficulty viewing information about a dot.
One solution would be to make the dots bigger. However, that will not solve the overlap issue. Another solution is to make the dimensions of the chart larger. ...
