The Graph is where you arrange your conversation flow and connect the Agent blocks together. It provides a visual representation of how the conversation will progress, allowing you to see the connections between different blocks and how they interact with each other.

​
Starting a Flow

It all begins with a Start Block block, which is the entry point of your flow. From there, you can add various blocks to create a dynamic and interactive conversation experience.

​
Adding Blocks

You can then drag and drop blocks from the left sidebar directly onto the graph. Connect blocks by clicking on the small circles at their edges. This creates a line that indicates the direction of the conversation flow. To delete a block, select it and press the Delete key, or click the block and choose the Delete icon from the block menu. You can move blocks by dragging them to new positions on the graph to reorganize your conversation flow as needed.
