This chart displays network throughput in megabits per second across four entities—Partner, PCL, GOLAN, and DriveU—over a short time period. Each entity is drawn as a distinct colored line using d3’s `line` generator, with the x-axis representing time via `scaleTime` and the y-axis set to a fixed range of 0 to 16. The data is parsed from a CSV file, and the visualization includes a color legend generated by a custom `colorLegend` function, with axes rendered using `axisLeft` and `axisBottom`. The SVG output is styled with thick, rounded line strokes.
