{"version":"1.0","type":"rich","title":"Log Scale Investigation","description":"This example presents a radial quadrant chart investigating log-scale relationships. The visualization combines car production data loaded via `d3.csv` with multiple concentric ring segments, colored to distinguish four quadrants. Each quadrant uses SVG gradients applied through `defs` and `linearGradient` elements. The chart constructs circular arcs using `d3.arc` with dynamically sized inner and outer radii, while custom x and y `d3.scaleLinear` scales define the underlying axis framework. The interface organizes three separate div containers—a slider, the SVG radar chart, and a bubble area—within a bordered wrapper, with the central chart rendering 900x900 pixel scaled via a viewBox.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9a4cacac68e41dba61a281a389e7654?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
