{"version":"1.0","type":"rich","title":"d3.js learning","description":"This stacked bar chart visualizes yearly fruit consumption data from a CSV-like dataset, tracking redDelicious apples, McIntosh apples, oranges, and pears. It uses `d3.layout.stack` to compute layered series and `d3.scale.ordinal` for the x-axis years, with SVG rects for bars. Hovering reveals a tooltip with the value via mouse events. A legend identifies the four categories with custom labels, while `d3.svg.axis` renders gridlines and axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7a5c505145142ca886e0ea519a846a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
