This visualization displays the 5-year inflation rate (T5YIE) over time as a smooth, curving line with colored dots marking each data point. The line uses a gradient stroke, while the circles are colored from blue to orange to red based on their position within the value range, with tooltips showing the date and rounded rate. Built with React and D3 v7, the code loads CSV data, applies time and linear scales, and renders the chart as SVG with custom axis components.
