This area chart visualizes gold prices over time, with the y-axis representing the "High" value and the x-axis representing timestamps. The chart’s filled area uses a smooth basis curve to connect data points. Built with D3 v5, the visualization employs `scaleTime` and `scaleLinear` for axes, and the `area` generator with `curveBasis` to create the path. Data is loaded via `csv` from a GitHub gist, and the SVG is rendered with grid lines and axis labels.
