{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"This bar chart visualizes the top 10 countries by 2020 population using data from the UN Population 2019 dataset, loaded via D3’s `csv` utility. Built with React and D3 v5, it encodes population with a linear x-scale (`scaleLinear`) and country names with a band scale (`scaleBand`) for the y-axis. The SVG rendering is composed of custom components for axes (`AxisBottom`, `AxisLeft`) and bars (`Marks`), with React state managing the asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74d4a9fbe5c74c56a6231e757f0c01c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
