This example visualizes an ETL workflow as an animated, interactive graph. It shows the dependencies between tasks in an Apache Airflow DAG, with colored nodes representing different task types (e.g., BashOperator, DummyOperator) and edges indicating execution order. The visualization uses the D3.js library to construct the node-link diagram within an SVG, with CSS transitions that highlight and fade elements to emphasize the flow. The underlying data, including task states like “success” and “skipped,” is sourced from a simulated Airflow run, and the graph is rendered using a force-directed layout.
