This example demonstrates a time series of percentiles (5th to 95th) as layered, colored areas, with a bold median line and animated markers showing client and server version releases. It uses a custom React application with the `d3.svg.area()` and `d3.svg.line()` APIs to render the smooth, interpolated bands, and animates the markers with `transition().attr()` over one second. The data comes from `data.json`, with release events from `markers.json`, and the visualization also includes a legend and axis clipping to keep the chart clear.
