This scatterplot visualizes the event timelines of multiple cases from a CSV dataset, mapping each event’s timestamp on the x-axis and its corresponding case on the y-axis. The visualization supports sorting cases by start time or duration via a dropdown menu, and users can highlight a specific activity, which changes the color of the event circles. Built with D3 v5, the code uses `d3.scaleTime`, `d3.scaleBand`, `d3.scaleOrdinal`, and `d3.axisBottom` to render the SVG, with hover tooltips and an animated color update for selected activities.
