Radial bar is simply a Bar Chart plotted on a polar coordinate system, rather than on a Cartesian one.
While they look cool, the problem with Radial Bar Charts is that the bar lengths can be misinterpreted. Each bar on the outside gets relatively longer to the last, even if they represent the same value.
