# XWUIChartLinesOnMapFlow

A lines-on-map flow chart backed by `XWUIChart` that draws weighted connections between geographic places, used to show movement or volume travelling from origins to destinations. Its data is graph-shaped: supply `nodes` (each with a `name` and `value`) and `links` (each `{ source, target, value }`), plus an empty `series`; you also pick a `block` (1-4) variant and a `size` preset.

## Basic Usage

Five nodes (sources A/B, a `Mid` hub, sinks X/Y) and four weighted links routing flow through `Mid` (60+40 in, 55+45 out).
