Multi-Line Graph: Making it Interactive
Explore methods to add interactivity to multi-line graphs in D3.js. Learn how to assign unique IDs to legend labels, handle user clicks to toggle graph lines, and apply smooth opacity transitions. This lesson helps you control graph visibility dynamically for clearer data display.
We'll cover the following...
