# XWUIDashboardCohortGrid

A cohort retention heat-grid for analytics dashboards. Rows are cohorts grouped by start period, columns are period offsets since each cohort started, and every cell is a retention percentage shaded by intensity, with a floating tooltip repeating the exact value on hover.

## Basic Usage

Five monthly cohorts tracked over eight weekly offsets, with the newest cohorts trailing off into not-yet-observed weeks (rendered as empty, dashed cells).

## Quarterly Retention

A smaller grid with quarterly cohorts, showing how the color intensity scales with strong long-term retention.

title: Quarterly Retention
description: Four quarterly cohorts tracked across four quarter-offsets, illustrating strong long-term retention with a denser, high-intensity heat pattern.
