This example visualizes the daily closing price of a financial asset over time as a smooth line chart. The visualization uses D3 v5 with a basisspline curve, rendered as an SVG path. It employs D3's `scaleLinear` and `scaleTime` for the axes, with an `axisBottom` and `axisLeft` that include gridlines. The chart also applies a custom color scheme for the line. The data is loaded from a local CSV file using D3's `csv` function and parsed for date and numeric values.
