# XWUIChartDotDensityMap

A dot-density-map chart variant backed by `XWUIChart` that scatters dots in proportion to a value across a gridded region, conveying where a quantity concentrates without shading whole areas. Supply one named `series` per grid row, each carrying its cells as `{ x, y }` points (column label and value), then choose a `block` (1-4) and `size` preset.

## Basic Usage

Five named rows, each with seven randomized cell values, forming a 5x7 field of density dots.

## Population Density Grid

Neighborhood population density over a 6-by-8 grid, concentrating dots over the urban core.

```

## Incidents by Zone and Shift

Support-ticket counts per zone across six daily shifts, revealing midday and afternoon peaks.
