This example visualizes Tesla’s historical stock closing prices as a line chart over time. It first shows the price trend across the date range, then uses D3.js v7 to load CSV data, parse dates, and map the values to a time-based x-scale and linear y-scale. The code draws the line with a steelblue stroke, adds axes and labels, and relies on `d3.csv`, `d3.timeParse`, `d3.scaleTime`, and `d3.line`. The rendering uses SVG, with the data sourced from a remote CSV file hosted on GitHub.
