Add TreeMaps to Looker! This powerful visualization provides an intuitive view of multi variable hierarchies. Our TreeMaps provide a drill-able hierarchy.

Custom Visualizations are currently supported for on-site deployments of Looker. Looker is releasing this capability shortly on their cloud deployment.

TreeMaps display hierarchical (tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches. A leaf node's rectangle has an area proportional to a specified dimension of the data. Often the leaf nodes are colored to show a separate dimension of the data.

When the color and size dimensions are correlated in some way with the tree structure, one can often easily see patterns that would be difficult to spot in other ways, such as if a certain color is particularly relevant. A second advantage of treemaps is that, by construction, they make efficient use of space. As a result, they can legibly display thousands of items on the screen simultaneously.
