{"version":"1.0","type":"rich","title":"Q2","description":"A stacked bar chart displays technology job counts across experience levels, using categorical colors to distinguish entry-level, intermediate, senior, and expert segments. The visualization loads CSV data with d3.csv, stacks series with d3.stack, and maps values through d3.scaleBand and d3.scaleLinear for axes. Hover interactions trigger a tooltip showing the exact category and count for each bar segment, rendered as SVG rectangles within the chart container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89363a57726c4fcd846efcb7c6617923?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
