This example visualizes San Francisco temperature readings over time using an SVG scatter plot built with D3.js v6. Each circle represents a temperature observation, positioned along a time-scaled x-axis and a linear temperature y-axis, with gridlines extending from the axis ticks. The chart includes labeled axes, a title, and uses scales (scaleTime, scaleLinear) and axes (axisLeft, axisBottom) from the D3 API. Data is loaded as CSV from a remote dataset, with timestamps and temperatures parsed before rendering the circle marks.
