{"version":"1.0","type":"rich","title":"Activity_6 Task 1","description":"This chart displays the populations of up to 30 countries as horizontal bars, ranked from largest to smallest. Each bar’s length encodes the 2020 population value, with a text tooltip appearing on hover to show the precise figure. The visualization is built with React and D3 v5, using `d3.scaleBand` for the categorical y-axis, `d3.scaleLinear` for the numeric x-axis, and SVG `rect` elements for the marks. Data is loaded asynchronously from a CSV file via `d3.csv`, and formatted using `d3.format` to abbreviate large numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c6fe04bfe9574603a400c70e5f045ec6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
