A sequences sunburst visualizes hierarchical path data from a metagenome sample collected on 9/11/15. The interactive ring chart displays the distribution of visit sequences, with each segment colored by category (home, product, search, account, other, end). Hovering over any arc highlights its ancestor path and updates a breadcrumb trail showing the percentage of total volume. Built with D3 v4, the visualization partitions data using `d3.partition()` and `d3.arc()`, while animation transitions fade non-ancestor segments over 1 second on mouse leave.
