This line chart displays wind speed measurements across the months of 2016, with each data point marked by a red circle that turns blue on hover. The chart uses D3.js v6 with an SVG rendering approach, loading CSV data from a GitHub gist. It applies d3.scaleLinear for both axes, d3.line to generate the path, and d3.csv for data ingestion, while axis ticks are built with d3.axisBottom and d3.axisLeft.
