A radial bar chart, or rose plot, displays categorical data as concentric, colored arcs. The length of each arc segment encodes the magnitude of the values for two series—View Counts and Bullet Counts—across categories like Carton, Life, and Game. Rendered as SVG, the visualization uses a custom `d3-scale-radial` scale to map magnitudes to radii, with the `d3.arc` function drawing each segment. The chart’s axes and circular grid lines are generated using `d3.scaleLinear` and `d3.scaleBand`, with labels and a legend for each series.
