This interactive sunburst chart visualizes the hierarchical flow of participants through post-high-school paths, with each arc segment representing a category such as Military, School, or Work. Hovering over a segment highlights its ancestral sequence in the breadcrumb trail and displays the percentage of the total population it represents. The visualization uses D3 v4’s `d3.partition` layout and `d3.arc` generator to render the radial layout, with data loaded from a nested JSON file via `d3.json`. A fade transition animates segment opacity on mouseleave, and a legend is toggled via checkbox.
