A time-based line chart displays four network performance metrics—Partner, PCL, GOLAN, and DriveU—measured in MBPS over a two-minute period. The visualization animates by smoothly translating the x-axis and line paths leftward, creating the effect of a moving time window. Data is loaded from a CSV file and parsed into JavaScript Date objects. The chart uses D3 v6 scales, axes, line generators with basis curves, ordinal color scales, and clip paths to reveal the moving portion, with a linear transition controlling the animation speed.
