Description

Currently, Kedro-Viz renders all nodes and datasets with the same default color scheme. This makes it difficult to visually distinguish between normal data pipelines and agent setup/agentic workflow components.

To improve clarity when working with agentic flows, we should allow custom colors for nodes and datasets in Kedro-Viz. This would make it easier to separate:

Agent setup nodes (e.g., intent detection, response generation context).

Regular ETL/ML pipeline nodes and datasets.

Context

In the customer support automation use case, the graph mixes data ingestion pipelines with agent orchestration pipelines. Colouring agent-related nodes differently from standard datasets will make the visualization much more readable and help explain workflows to developers and non-technical stakeholders.
