{"version":"1.0","type":"rich","title":"Refactored Barchart step 2","description":"This example presents a horizontal bar chart displaying population data for the top 10 countries from a UN 2019 dataset. Using D3.js v7 for scales and SVG rendering within a React component, the chart separates axis and mark rendering into modular functions. The bottom axis shows linear population values, while the left axis displays categorical country names using a band scale. React's useState hook manages the asynchronously loaded CSV data, which is parsed and sliced before being converted into rectangular SVG elements via the Marks component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f50f57f0a690492487ec884f15007d69?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
