Test 001
This chart displays one week of temperature data in San Francisco, plotting time on the x-axis and degrees Celsius on the y-axis. Using D3 v5, the code loads CSV data and renders an SVG line chart with a smooth basis curve, alongside labeled axes and grid lines. The visualization employs `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` from the D3 library, with the data sourced from Data Canvas - Sense Your City.
