{"version":"1.0","type":"rich","title":"3rd graph","description":"This example presents a responsive stacked bar chart that visualizes population data for various countries across multiple years, from 1980 through projected figures for 2050. The chart uses a color-coded ordinal scale to distinguish each year's segment within the stacked bars. Built with D3 v6, the visualization loads its dataset from a remote CSV file and renders the graphic as an SVG. The code utilizes `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.stack` to compute the stacked series, with axis labels and interactive hover effects that highlight individual bars.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f75bcb1db1c642598ba3d35ed10fc2fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
