This example shows the price of Bitcoin over the past week, tracing a smooth, curved line across a time-based x-axis and a rate-based y-axis. The chart includes labeled axes, grid lines, and a title. Built with D3 v5, it loads CSV data from a GitHub gist and uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a line generator with `curveBasis` to render an SVG line chart.
