This example shows a line chart of sales data over time, with a year-based x-axis and a numeric sales y-axis. Data is loaded from a CSV file and parsed using D3’s `csv` and `timeParse`. The chart uses `scaleTime` and `scaleLinear` for axes, `line` to generate the path, and `axisBottom` and `axisLeft` for ticks. Styled with purple tick labels, brown grid lines, and an orange stroke, the visualization is rendered as an SVG with D3 v5.
