A line chart displays the opening bid price of EUR/USD throughout 2021, with months on the x-axis and price on the y-axis. The visualization uses React to manage state and D3 v7 functions including `scaleTime`, `scaleLinear`, `extent`, and `line` with `curveBasis` to render a smooth SVG path. CSV data is fetched from a GitHub gist, sorted chronologically by date, and mapped to positional scales. Purple axis labels and a red line style highlight the price trend over the twelve-month period.
