# XWUIChartSymbolMap

A symbol map chart: a fixed-type wrapper around `XWUIChart` that places sized and styled symbols at positions to encode a value by symbol magnitude, a proportional-symbol style of spatial display. Supply `{ series }` of `{ x, y }` points plus a `block` preset (1-4) and `size`. Use it to mark locations or positions where each point's value is shown through its symbol rather than a bar or line.

## Basic Usage

This example positions the two series, Series A and Series B, as proportional symbols across the plot, with each of the six monthly points (Jan through Jun) drawn as a symbol whose magnitude reflects its value at medium size.

## Earthquake Magnitude by City

Each city is drawn as a single symbol sized by the strongest quake ever recorded there, turning the magnitude scale into a proportional map where the great megathrust events tower over the rest.

## Store Revenue by Metro

Two retail formats - flagship and outlet - are plotted side by side as proportional symbols per metro, comparing which markets each channel dominates.

description: Flagship and outlet revenue per metro drawn as proportional symbols, so channel strength by market is easy to compare.
