This line chart shows temperature readings in San Francisco over time, with a green stroke and tooltips displaying exact values. The visualization supports panning and zooming through a scale-bound interval selection. Built with the vega-lite-api and rendered using vega and vega-lite, it loads CSV data from a VizHub-hosted dataset. The code customizes axis titles, date formatting, and color scheme via config.js, while getData.js uses d3.csv to fetch the data.
