This fork of a line chart visualizes the relationship between policy numbers (dates on the x-axis) and insured values (y-axis), using example data loaded from a CSV file. The visualization is rendered as scalable vector graphics (SVG). The code employs D3 v5 functions like `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to construct and plot the chart, with a red line path representing the data trend. Both axes include labeled ticks and custom margins define the plotting area.
