This example shows the opening bid price of EURUSD across the months of 2021 using a line chart built with React and D3 version 7. The chart fetches CSV data from a GitHub gist, formats dates and numeric values, and renders an SVG with a smooth curve, gold tick lines, blue labels, and red stroke marks. It implements custom axes and scales via `d3.scaleTime` and `d3.scaleLinear`, with tick formatting through `d3.timeFormat` and line generation using `d3.line` with `curveBasis`.
