This interactive visualization renders a branching tree fractal on an HTML5 Canvas. Mouse movement dynamically changes the branch length ratio and angle difference, altering the tree's shape in real time. The code uses the Canvas API’s `getContext('2d')`, `moveTo`, `lineTo`, and `stroke` methods to draw recursive branches. The tree structure emerges from a recursive `drawTree` function that splits into left and right branches until reaching a depth of zero, with each branch’s length and angle determined by cursor position.
