The Grid layout embeds a visualization at the top of the page that shows content as boxes in a grid. Colored lines are drawn representing connections between the current page and its related content. The rest of the page follows the Basic layout, with text and media interspersed.
The grid visualization displays all content in the book in a grid format where each box represents a piece of content, color-coded by type. The darker the box, the more connections it has to other content (relative to the other boxes). Each line represents a connection, color-coded by type. You can roll over or click the boxes to browse connections, or click to add more content to the current selection, allowing multiple sets of relationships to be viewed simultaneously. To deselect a box, simply click it again.
