{"version":"1.0","type":"rich","title":"d3.js learning","description":"This example demonstrates a stacked bar chart built with D3.js, visualizing changes in fruit production (apples, oranges, and pears) over multiple years. The chart uses D3’s `d3.layout.stack` to create the stacked series, `d3.scale.ordinal` for the x-axis, and `d3.svg.axis` for the axes. Hovering over a bar segment reveals a tooltip displaying the exact value. The chart is rendered as SVG, with a legend identifying each fruit series and colors assigned to each category.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af1880cd0b334eb293694b0e1148e07d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
