This example demonstrates a connected scatterplot showing how a numeric value changes over time, with a time-scaled X axis and linear Y axis. The visualization renders as an SVG using D3 v7, loading CSV data from a remote GitHub repository. The code uses `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and `d3.axisBottom`/`d3.axisLeft` to draw the line and circular points. It also uses `d3.timeParse` to format dates and `d3.csv` for asynchronous data loading.
