This example visualizes temperature trends over time using the Vega-Lite API, rendering a line chart from CSV data. The visualization encodes timestamps on the x-axis and temperature values on the y-axis, with tooltips displaying temperature details. It uses the `vega-lite-api` library alongside `d3.csv` for data loading, with a custom dark theme applied through a configuration file. The chart fills the browser window and updates dynamically, leveraging Vega’s rendering capabilities with SVG output.
