This line chart visualizes gold prices over time, plotting the "High" value against the timestamp for each data point. The visualization uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` for axes, a `line` generator with `curveBasis` for the smoothed path, and `axisBottom` and `axisLeft` for labeled ticks. Data is loaded via `csv` from a GitHub gist, with the chart styled through CSS properties like stroke color and font sizing defined in an external stylesheet.
