The visualization displays every spell cast in the Harry Potter series as a single point, arranged along a horizontal axis by story position and grouped by book and spell name in the left panels. It uses the KSHF framework to load data from a Google Spreadsheet and renders an interactive concordance, where users can search or click to zoom into details. The implementation relies on D3’s force simulation for layout and a custom list view for records, with sortable columns for position and ID.
