# XWUIChartBubbleMap

A map-oriented chart variant backed by `XWUIChart` that places sized bubbles at positions to encode a magnitude at each location, the standard way to show quantity across a geography or coordinate space. Provide a `series` of `{ x, y }` points and pick a `block` (1-4) and `size` preset.

## Basic Usage

A single series of 30 randomized points plotted as a bubble map.

## City Populations

Eight world cities are placed by longitude with population (millions) as the bubble height, with grid values shown on the interactive map.

## Store Sales by Location

Retail stores spread across a regional coordinate axis with monthly sales as the bubble height and a "k" unit on the readout.
