## Overview

React Virtualized is a React component library for rendering large scrollable collections efficiently. A consumer imports a component, supplies data and layout/rendering props, and receives a virtualized view; the central Grid capability supports the list and tabular-data use cases. The public exports and component families are evidenced by source/index.js and the tree. Internal wiring among most components was not sampled, so the graph avoids asserting those call relationships.

Main entry points: [`source/index.js`](https://github.com/bvaughn/react-virtualized/blob/master/source/index.js) (Public exports), [`source/Grid/Grid.js`](https://github.com/bvaughn/react-virtualized/blob/master/source/Grid/Grid.js) (Grid), [`source/List/List.js`](https://github.com/bvaughn/react-virtualized/blob/master/source/List/List.js) (List), [`source/Collection/Collection.js`](https://github.com/bvaughn/react-virtualized/blob/master/source/Collection/Collection.js) (Collection)
