Ashish-Soni08/ggradialbar: A ‘ggplot2’ Radial Bar Chart Extensions for Visualizing High-dimensional Clusters and Their Evolution

Implementation of a normal and an interactive radial barchart visualization as ggplot2 geoms. The barchart provides a graphical representation of a subpopulation. In particular, the height of a bar depicts the subpopulation average for a feature. Each feature is z-score normalized. The radial spatial layout distributes the bars around a circle where each bar starts at the black 0 line which represents the feature average over the whole population. Due to feature scaling, bars inclined to the outside represent feature averages above the overall population mean and bars inclined to the inside represent feature averages below the population mean. This interpretation can optionally be visually supported by color-coded bars. Feature names can optionally be shown on top of each bar. All values are depicted in terms of standard deviation away from the population mean. For example, a value of -1 indicates that the subpopulation average is 1 standard deviation smaller than the overall population average. The standard deviation within a subpopulation is represented as grey error lines facing the colored inner circle. To facilitate quick feature localization, a custom feature categorization can be provided (see inner circle), alongside the subpopulation title and the number of instances within that subpopulation.
