This visualization displays network throughput data for four providers—Partner, PCL, GOLAN, and DriveU—as overlapping time-series lines with a seismograph aesthetic. The chart uses d3.scaleTime for the time axis and d3.scaleOrdinal with a categorical color scale to distinguish each provider. The data is sourced from a CSV file and processed into numeric values before being plotted. The implementation leverages d3.line with curveBasis, SVG rendering, and custom axes with tick formatting, along with a colorLegend module for the categorical mapping.
