This decision tree visualization shows how a cardiovascular disease model classifies patients based on their cholesterol type. The tree branches from a root node into "Yes" and "No" splits, leading to leaf nodes colored green for "Normal" and blue for "Heart Disease," with each node displaying sample counts and percentages. The visualization uses D3.js v6 with an SVG rendering, employing `d3.tree()` layout, `d3.hierarchy()` for data structuring, and `d3.linkHorizontal()` for the curved connecting paths. Circles and text labels represent nodes, with leaves colored according to their classification type.
