A line chart displays the opening bid price of EURUSD across the months of 2021 in a React application. The SVG rendering uses D3 v7 to create scales with d3.scaleTime and d3.scaleLinear, while the smooth curve is generated with d3.line and curveBasis. Data is loaded from a CSV file via d3.csv, with dates parsed and sorted ascending. Axis ticks and labels are colored gold and blue respectively, with the line drawn in red.
