This example visualizes temperature data from the San Francisco week_temperature_sf CSV dataset using a Vega-Lite area chart. The chart plots temperature values over time, with a tooltip displaying the exact temperature for each data point. The visualization is built using the vega-lite-api library, which wraps Vega-Lite and Vega, and is configured with custom styling for axis labels and titles. Data is loaded asynchronously via d3.csv, and the chart is rendered as an SVG that fits the full browser window.
