Bubble
Bubble charts are scatter charts which display data as points with coordinates and sizes that are defined by the value of their items.
The Bubble charts are well suited for displaying dozens to hundreds of values. They come in handy especially when you wish to visualize size values, differing by several orders of magnitude. As the size value is represented by a circle area, it is a best practice to plot positive values.
