This document discusses JGrid, an open source Java Swing component for grid-based visualization of data. JGrid provides an alternative to using JList for non-hierarchical data and shares interfaces with JList. It uses renderers similarly to JList to display raw data in grid cells. The document demonstrates examples of grid views and discusses when grids are preferable to lists or tables for displaying data. It also outlines plans to further develop JGrid with additional features like sorting, filtering and cell editing.
