This line chart visualizes Google’s annual user counts from 2011 to 2021, loaded from a GitHub-hosted CSV file using d3.csv. It renders an SVG with d3.scaleTime for the x-axis (years) and d3.scaleLinear for the y-axis (users), alongside d3.axisBottom and d3.axisLeft with gridlines. A d3.line generator creates the path, while axis labels and a title are added via SVG text elements. The chart employs d3.extent and d3.max to set domain bounds and custom margins for layout.
