This dendrogram visualizes a hierarchical clustering of the Flare data set, showing the nested structure of its analytics, animation, and visualization classes. Internal nodes are rendered as small circles, with connecting links drawn as smoothed curves, while leaf nodes display labels. The example uses D3 v4 and SVG rendering, employing the `d3.cluster` and `d3.stratify` layouts to position nodes based on their hierarchical depth and computed height. Data is loaded from a CSV file, and the chart’s orientation places the root at the left, expanding rightward.
