Axis components render tick lines and labels through custom JSX, while SVG rectangles in the Marks component include native tooltips via `<title>` elements, with population values formatted in billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/384ea3f64e7f486b876c9882476653db?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
