This line chart displays Bitcoin prices from March 2025, using a monotone curve to smoothly connect daily price points over time. The visualization includes a grid with dashed horizontal lines, a formatted y-axis showing price values with comma separators, and rotated date labels on the x-axis for readability. Built with D3 v7, the chart loads CSV data via `d3.csv`, parses dates with `d3.timeParse`, and renders the path using `d3.line` with `d3.curveMonotoneX`. The SVG output applies a brown stroke to the line and uses time and linear scales to map data to screen coordinates.
