By default, D3 comes with around a dozen built-in layouts that cover most common visualizations. They can be split roughly into normal and hierarchical layouts. Normal layouts represent data in a flat hierarchy, whereas hierarchical layouts generally present data in a tree-like structure.
The normal (non-hierarchical) layouts are as follows:
- Histogram
- Pie
- Stack
- Chord
- Force
The hierarchical layouts are as follows:
- Tree
- Cluster
- Tree map
- Partition
- Pack
We will create a boatload of examples over the next two chapters. We start with hierarchical layouts (located in the d3-hierarchy module) because they're the most consistent in terms of data structure, which looks something like this:
{ "name": "Tywin Lannister", "children": ...
