{"version":"1.0","type":"rich","title":"Fork of Fork of Vega-Lite API Template","description":"This visualization displays the US population by age, sex, and year from 1850 to 2000, using grouped bars to compare age cohorts over time. Built with the Vega-Lite API, it encodes year on the x-axis, population counts on the y-axis, and age groups as color, with tooltips revealing sex and population values. The code loads CSV data via `d3.csv` from a GitHub gist, configures axes and label styling through the `config` object, and renders the chart using the Vega, Vega-Lite, and Vega-Tooltip libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2320bb41f77d4ac3abf6e414fb07a468?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
