What is a prediction cone in visualization?

It's an expanding shape from a point, showing possible future paths with widening uncertainty — key for AI trajectories, racing, aviation.

How do I use the prediction cone JavaScript library?

Include the script, init on a canvas/SVG with config object for angle, length, colors. Framework-free, embed in any HTML.

Are there other safe triangle JS libraries?

Slim pickings pre-this; mostly framework snippets. This one's the pure JS pioneer — star it, contribute.
