{"version":"1.0","type":"rich","title":"Tutorial1","description":"This bar chart displays the 2020 populations of 30 countries, with a horizontal layout and a square-root scale for the x-axis. The visualization utilizes React, D3 v5, and ES6 modules, loading data from a CSV in useData.js using d3.csv. SVG rendering is driven by custom components for axes and marks, which use d3.scaleBand and d3.scaleLinear to map values. A tooltip, set via the `title` element, shows the formatted population on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7089cfc977914fc1bf96f18291fca3a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
