+# Force Directed Graphs
+
+## Describe a Force Directed Graph
+
+- A force directed graph is a graph that is affected by various forces (e.g. gravity, repulsion, etc)
+- It can be extremely useful when setting up graphs of relationships
+
+## Describe how a to set up a graph of relationships
+
+### Display
+
+- We're going to have a list of nodes representing people and display them as circles
+- We're going to have a list of links representing connections between people and display them as lines
+
+### Physics
+
+- We're going to have a gravitational force at the center of the `svg` that draws all nodes towards it
+- We're going to have forces on each node so that they repel each other
+- We're going to have link forces that connect each of the nodes so that they don't repel each other too much
