{"version":"1.0","type":"rich","title":"Largest Population in the USA","description":"This visualization displays the largest cities in the USA by 2020 population using a bar chart, where each bar represents a state and shows population values on the y-axis, colored by individual city. The data comes from World Population Review via a CSV hosted on GitHub. Built with D3.js and Vega-Lite, it uses the API’s `markBar` and `encode` methods to map city and state fields, with tooltips revealing population and city names. The chart is configured with custom styling for readability, including dark text and light gray axis ticks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ce181617871474c84fd132976b21512?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
