Interactive Color Legend with EdX Viewer Data
An interactive scatterplot displays video plays versus active days for EdX users in 2013, with each circle’s color representing a course. Hovering over the ordinal color legend fades non-matching points and overlays a highlighted subset. Built with React and D3 v5 (scaleLinear, scaleOrdinal), the SVG renders axes via custom components and circles with native HTML titles for tooltips. Data originates from the MITx-HarvardX Dataverse repository.
