{"version":"1.0","type":"rich","title":"activity 6 task1 tutorial 1","description":"This example shows a horizontal bar chart of 2020 population data by country, with bars colored light green and blue axis lines. The visualization uses React to render an SVG scene, loading data through a custom `useData` hook and building scales with `d3.scaleBand` and `d3.scaleLinear`. Axis components are modularized, and the x-axis labels use D3's `format('.2s')` to abbreviate population values, replacing 'G' with 'B'. The chart is constructed entirely with D3 v5 and React, demonstrating ES6 module imports and component-based structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cf504858fae846c08404175d589b4d3f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
