This visualization displays temperature data over time as a filled area chart, with the y-axis encoding temperature and the x-axis encoding timestamps from the CSV dataset. Built with the Vega-Lite API, it uses `vl.x().fieldT()` and `vl.y().fieldQ()` for temporal and quantitative encodings, and includes a tooltip via `vega-tooltip`. The code fetches data using `d3.csv`, applies custom axis and label styling through a config object, and renders the chart to fill the browser window.
