Title
This example renders a placeholder visualization from a CSV file containing integration flow data, showing application connections and data objects. The code uses D3 v5's `select` and `csv` methods to load the dataset into an SVG canvas, though it only appends fixed-size rectangles without mapping data attributes. The visualization currently provides minimal graphical output, with the data logged to the console but not visually encoded. The implementation relies on D3's promise-based `csv` loader and basic SVG shape creation.
