A radar chart shows multivariate data of three or more quantitative variables mapped onto an axis.

For a radar chart we must define anrx.recharts.radar() component for each set of values we wish to plot. Eachrx.recharts.radar() component has adata_key which clearly states which variable in our data we are plotting. In this simple example we plot theA column of our data against thesubject column which we set as thedata_key inrx.recharts.polar_angle_axis.

We can also add two radars on one chart by using tworx.recharts.radar components.

In this plot aninner_radius and anouter_radius are set which determine the chart's size and shape. Theinner_radius sets the distance from the center to the innermost part of the chart (creating a hollow center if greater than zero), while theouter_radius defines the chart's overall size by setting the distance from the center to the outermost edge of the radar plot.

Thedot prop shows points at each data vertex when true.legend_type="line" displays a line in the chart legend.animation_begin=0 starts the animation immediately,animation_duration=8000 sets an 8-second animation, andanimation_easing="ease-in" makes the animation start slowly and speed up. These props control the chart's appearance and animation behavior.

Chart data tied to a State var causes the chart to automatically update when thestate changes, providing a nice way to visualize data in response to userinterface elements. View the "Data" tab to see the substate driving thisradar chart of character traits.
