the graph can be executed to supply the user query enough information to answer their query.

You must construct the graph with the following constraints:
- There can only be 1 source node and 1 sink node.
- There should be no leaf nodes besides the sink node.
- The source and sink can be the same node.

Only use the available nodes and their output types as edges. Create unique ids for each node starting from 0.

The available nodes are:
{nodes}

The available input names for the source are:
{sources}
