NveilSpec¶

NveilSpec ¶

NveilSpec(spec_blob)

Opaque visualization specification with local rendering.

Once generated, spec.render(new_data) is 100% local — no API call, no cost. Reusable on any data with compatible columns.

explanation

Human-readable description of what was generated.

render(data=None)

Render using the auto-detected best backend (ECharts, VTK, DeckGL).

100% local execution — no API call.

If called within a session context (with nveil.session()), reuses the session's already-computed pipeline outputs — no pipeline re-run.

PARAMETER	DESCRIPTION
`data`	pandas DataFrame, dict of DataFrames, numpy array, or list. TYPE: `Any` DEFAULT: `None`

RETURNS	DESCRIPTION
`Any`	Backend-specific figure object (ECharts option dict, pydeck
`Any`	`Deck` / `Layer`, VTK viz dict, or graph / html payload).
