{"version":"1.0","type":"rich","title":"Bar Chart Demo","description":"This bar chart shows the populations of the ten most populous countries, using data from the United Nations’ 2018 estimates. It uses D3 v5 with an SVG rendering, employing `d3.scaleLinear` and `d3.scaleBand` to map population values and country names to visual bars. The axes are customized via `d3.axisBottom` and `d3.axisLeft`, with tick labels formatted using `d3.format` to display numbers in billions. The chart draws steelblue bars without labels, omitting axis lines and ticks for a clean look.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f860edd49f4c4e87940dbb7a1548aab6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
