Line Chart with Multiple Lines
This line chart displays how vessel valuations change over time, with each line representing a different vessel and color-coded according to a categorical scale. The data comes from a CSV file loaded from VizHub. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line` with `curveBasis`, `nest` for grouping, and `axisLeft`/`axisBottom` for axes, rendering to SVG with a custom `colorLegend` function.
