The graph is too cluttered to read

use the key filter to keep only the fields you care about, or remove noisy fields like `debug`, `trace`, and `metadata`. If the payload is huge, filter it first with `jq '.data.items[:5]'` to get a representative sample.

The key list is empty

check that the input is valid JSON and contains object keys. Arrays of objects work; arrays of primitives like `[1, 2, 3]` do not expose keys.

Nothing renders after pasting

your JSON is malformed. Check the error indicator. Common issues: trailing commas, unquoted keys, single quotes instead of double.

The browser gets slow with my JSON

very large payloads (thousands of nodes) can lag the renderer. Trim the data before visualizing. For files over a few MB, use a desktop tool like VS Code's JSON outline.

Nodes are overlapping

try zooming out or panning to a less crowded area. The layout algorithm positions nodes automatically but can get cramped with wide, shallow structures.
