# XWUIChartVelocityTime

A velocity-time chart backed by `XWUIChart` that plots a rate against time, the familiar kinematics / throughput view where the slope reads as acceleration and the area as distance or total work. Provide named `series` of `{ x, y }` points and pick a `block` (1-4) variant plus a `size` preset; legend and grid auto-toggle per block unless overridden.

## Basic Usage

Two named monthly series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - plotted as velocity over time.
