It runs Vega-Lite and Vega JavaScript libraries inside a v8 runtime, then handles font metrics and SVG-to-PNG conversion. The package is self-contained\u2014it needs no external web browser, Node.js, or system dependencies beyond what the wheels provide.\n\nYou can use it to export charts from Altair (which generates Vega-Lite JSON) or from raw Vega-Lite specifications. The main functions convert a specification string and optional parameters like scale for PNG resolution or vl_version to target a specific Vega-Lite schema version.","worth_installing":"Yes, if you need to export Vega-Lite or Altair charts to static images without a browser or Node.js dependency. The package is dependency-free at runtime, has no known vulnerabilities, and works on common platforms. Install friction is moderate due to compiled wheels, but pre-built binaries are available. Maintenance is aging (205 days since last release, minimal repository activity), so expect slower response to issues, but the core functionality is stable."},"id":"vl-convert-python","links":{"html":"https://skillfed.io/packages/vl-convert-python","md":"https://skillfed.io/packages/vl-convert-python.md","pypi":"https://pypi.org/project/vl-convert-python/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-01-21","license_spdx":null,"license_treatment":"permissive","name":"vl-convert-python","python_support":"supports_current","summary":"Convert Vega-Lite chart specifications to SVG, PNG, or Vega"},"popularity":{"monthly_downloads":1389181,"position":3969,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.9.0.post1"}
