This scatter plot shows the evolution of temperature in San Francisco over time, with each point representing a daily measurement. The visualization uses a time-based x-axis and a linear temperature scale on the y-axis. The code leverages D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` to construct the chart, rendering circles as SVG elements with a semi-transparent gold fill. Data comes from a CSV dataset on VizHub, which is parsed and converted to appropriate date and numeric types before rendering.
