This visualization displays temperature data from San Francisco over time, drawing a smooth line through the points using D3’s line generator with curveBasis. The SVG render includes labeled axes, gridlines from axis tick marks, and a title. The code imports specific D3 v5 functions like scaleTime, scaleLinear, axisLeft, and axisBottom, and loads the dataset from a CSV file via d3.csv. The scatter plot’s underlying data comes from the UCI Machine Learning Repository’s Auto MPG dataset, though the visual focuses on timestamp versus temperature.
