{"version":"1.0","type":"rich","title":"D3 Course 1: Bar Chart","description":"This bar chart displays the population of ten countries, using horizontal bars sorted alphabetically by country name. The visualization is built with D3 v5, loading data from a CSV file and rendering it as SVG. It uses `d3.scaleLinear` and `d3.scaleBand` for positioning, `d3.axisLeft` and `d3.axisBottom` for axes, and `d3.format` to abbreviate large numbers (e.g., converting billions to “B”). The chart includes a title, axis label, and grid lines, with a margin convention applied to the SVG layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8d2787fdcee842efb4bc76fa72feabed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
