    "\n",
    "This notebook introduces the ipyplotly enhancements to the plotly.py visualization library and demonstrates some of its features.\n",
    "\n",
    "\n",
    "## New Features\n",
    "\n",
    " - Traces can be added and updated interactively by simply assigning to properties\n",
    " - The full Traces and Layout API is generated from the plotly schema to provide a great experience for interactive use in the notebook\n",
    " - Data validation covering the full API with clear, informative error messages\n",
    " - Jupyter friendly docstrings on constructor params and properties\n",
    " - Support for setting array properties as numpy arrays. When numpy arrays are used, ipywidgets binary serialization protocol is used to avoid converting these to JSON strings.\n",
    " - Context manager API for animation\n",
    " - Programmatic export of figures to static SVG images (and PNG and PDF with cairosvg installed)."
