{"version":"1.0","type":"rich","title":"Stacked Barchart Vega-Lite API Template","description":"This stacked bar chart visualizes population distribution across countries by religion, using data from the UCI Machine Learning Repository’s Auto MPG dataset via a Gist. Built with the Vega-Lite API and D3.js (d3.v5), it encodes country on the x-axis, population on the y-axis, and religion as color, with tooltips showing population values. The visualization renders as an SVG, with custom font sizes and axis styling from a config file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f44c9581b9a24d9bb13c9f344109a196?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
