A Sankey diagram traces student enrollment flows from Del Val Charter in the 2014-15 school year to various destinations in the following year, including other schools, graduation, or unknown outcomes. The visualization uses D3 v5 with the sankey plugin to render SVG nodes and curved links, whose thickness scales with student counts. Nodes are color-coded by school name and draggable, triggering a relayout that recalculates link paths. The data comes from a JSON file containing over sixty school names and their weighted connections.
