Fork of Vega-Lite API Template
✓ Published0🌍 Public
This example visualizes U.S. state population trends from 2010 to 2019 using a multi-series line chart. The Vega-Lite API constructs marks encoded with x-axis time data, y-axis population values, and color grouping by geographic area, with tooltips for individual states. Population data is loaded asynchronously via d3.csv from a GitHub gist. The visualization renders in SVG and includes a dark-themed config that removes axis domains and customizes label styling for readability.
