VarshaG3D is an interactive 3D column chart visualizing download counts for seven popular apps across six different app stores. The chart presents grouped, non-stacked vertical bars in three-dimensional space, with each group representing an app and each column within the group representing a source. Built with Highcharts and the Highcharts 3D module, the visualization uses `options3d` to set alpha, beta, and depth parameters, with `groupZPadding` separating the store categories along the z-axis. The code defines series for each store, including App Store, Playstore, OneStore, Softonic, GalaxyStore, and VivoStore, with the app names set as x-axis categories.
