This fork visualizes the opening bid price of EURUSD across 2021 as an area chart. A smooth basis curve traces the price trend over months, with a semi-transparent aqua fill beneath the line. The chart uses D3 v5’s `scaleTime` and `scaleLinear` for axes, `area` and `curveBasis` to generate the filled path, and `axisLeft`/`axisBottom` for the labeled ticks. Data is loaded from a Gist-hosted CSV, and axes are rendered on an SVG canvas with custom tick styling.
