This example demonstrates a scatterplot of temperature readings for various cities, using the Vega-Lite API to construct the visualization. The chart encodes temperature as the y-axis and city as the x-axis, with a tooltip displaying the state for each point. The code fetches CSV data from a remote URL using `d3.csv`, then builds the visualization with `vega-lite-api`, rendering it as an SVG via the `vega` and `vega-lite` libraries. Styling is customized through a config object, and the chart fills the browser window with an autosize fit.
