This example presents an interactive timeline visualization of temporal data, showing the start and end times for multiple entities (such as people) as horizontal bars. Users can zoom and navigate through the time range using provided controls. The visualization is built with D3.js v5, using SVG for rendering and the `scaleTime` and `scaleOrdinal` APIs for time scaling and color assignment. A dropdown menu, created with a custom D3 component, allows users to filter data, while the timeline supports stacked rows and time axis navigation.
