+    config: dict or None (default None)
+        Plotly.js figure config options
+    auto_play: bool (default=True)
+        Whether to automatically start the animation sequence on page load
+        if the figure contains frames. Has no effect if the figure does not
+        contain frames.
+    include_plotlyjs: bool or string (default True)
+        Specifies how the plotly.js library is included/loaded in the output
+        div string.
+
+        If True, a script tag containing the plotly.js source code (~3MB)
+        is included in the output.  HTML files generated with this option are
+        fully self-contained and can be used offline.
+
+        If 'cdn', a script tag that references the plotly.js CDN is included
+        in the output. The url used is versioned to match the bundled plotly.js.
+        HTML files generated with this option are about 3MB smaller than those
+        generated with include_plotlyjs=True, but they require an active
+        internet connection in order to load the plotly.js library.
+
+        If 'directory', a script tag is included that references an external
+        plotly.min.js bundle that is assumed to reside in the same
+        directory as the HTML file.
+
+        If 'require', Plotly.js is loaded using require.js.  This option
+        assumes that require.js is globally available and that it has been
+        globally configured to know how to find Plotly.js as 'plotly'.
+        This option is not advised when full_html=True as it will result
+        in a non-functional html file.
+
+        If a string that ends in '.js', a script tag is included that
+        references the specified path. This approach can be used to point
+        the resulting HTML file to an alternative CDN or local bundle.
+
+        If False, no script tag referencing plotly.js is included. This is
+        useful when the resulting div string will be placed inside an HTML
+        document that already loads plotly.js. This option is not advised
+        when full_html=True as it will result in a non-functional html file.
+    include_mathjax: bool or string (default False)
+        Specifies how the MathJax.js library is included in the output html
+        div string.  MathJax is required in order to display labels
+        with LaTeX typesetting.
+
+        If False, no script tag referencing MathJax.js will be included in the
+        output.
+
+        If 'cdn', a script tag that references a MathJax CDN location will be
+        included in the output.  HTML div strings generated with this option
+        will be able to display LaTeX typesetting as long as internet access
+        is available.
+
+        If a string that ends in '.js', a script tag is included that
+        references the specified path. This approach can be used to point the
+        resulting HTML div string to an alternative CDN.
+    post_script: str or list or None (default None)
+        JavaScript snippet(s) to be included in the resulting div just after
+        plot creation.  The string(s) may include '{plot_id}' placeholders
+        that will then be replaced by the `id` of the div element that the
+        plotly.js figure is associated with.  One application for this script
+        is to install custom plotly.js event handlers.
+    full_html: bool (default True)
+        If True, produce a string containing a complete HTML document
+        starting with an <html> tag.  If False, produce a string containing
+        a single <div> element.
+    animation_opts: dict or None (default None)
+        dict of custom animation parameters to be passed to the function
+        Plotly.animate in Plotly.js. See
+        https://github.com/plotly/plotly.js/blob/master/src/plots/animation_attributes.js
+        for available options. Has no effect if the figure does not contain
+        frames, or auto_play is False.
+    default_width, default_height: number or str (default '100%')
+        The default figure width/height to use if the provided figure does not
+        specify its own layout.width/layout.height property.  May be

+        A string representing a local file path or a writeable object
+        (e.g. a pathlib.Path object or an open file descriptor)
+    config: dict or None (default None)
+        Plotly.js figure config options
+    auto_play: bool (default=True)
+        Whether to automatically start the animation sequence on page load
+        if the figure contains frames. Has no effect if the figure does not
+        contain frames.
+    include_plotlyjs: bool or string (default True)
+        Specifies how the plotly.js library is included/loaded in the output
+        div string.
+
+        If True, a script tag containing the plotly.js source code (~3MB)
+        is included in the output.  HTML files generated with this option are
+        fully self-contained and can be used offline.
+
+        If 'cdn', a script tag that references the plotly.js CDN is included
+        in the output. The url used is versioned to match the bundled plotly.js.
+        HTML files generated with this option are about 3MB smaller than those
+        generated with include_plotlyjs=True, but they require an active
+        internet connection in order to load the plotly.js library.
+
+        If 'directory', a script tag is included that references an external
+        plotly.min.js bundle that is assumed to reside in the same
+        directory as the HTML file.  If `file` is a string to a local file
+        path and `full_html` is True, then the plotly.min.js bundle is copied
+        into the directory of the resulting HTML file. If a file named
+        plotly.min.js already exists in the output directory then this file
+        is left unmodified and no copy is performed. HTML files generated
+        with this option can be used offline, but they require a copy of
+        the plotly.min.js bundle in the same directory. This option is
+        useful when many figures will be saved as HTML files in the same
+        directory because the plotly.js source code will be included only
+        once per output directory, rather than once per output file.
+
+        If 'require', Plotly.js is loaded using require.js.  This option
+        assumes that require.js is globally available and that it has been
+        globally configured to know how to find Plotly.js as 'plotly'.
+        This option is not advised when full_html=True as it will result
+        in a non-functional html file.
+
+        If a string that ends in '.js', a script tag is included that
+        references the specified path. This approach can be used to point
+        the resulting HTML file to an alternative CDN or local bundle.
+
+        If False, no script tag referencing plotly.js is included. This is
+        useful when the resulting div string will be placed inside an HTML
+        document that already loads plotly.js.  This option is not advised
+        when full_html=True as it will result in a non-functional html file.
+
+    include_mathjax: bool or string (default False)
+        Specifies how the MathJax.js library is included in the output html
+        div string.  MathJax is required in order to display labels
+        with LaTeX typesetting.
+
+        If False, no script tag referencing MathJax.js will be included in the
+        output.
+
+        If 'cdn', a script tag that references a MathJax CDN location will be
+        included in the output.  HTML div strings generated with this option
+        will be able to display LaTeX typesetting as long as internet access
+        is available.
+
+        If a string that ends in '.js', a script tag is included that
+        references the specified path. This approach can be used to point the
+        resulting HTML div string to an alternative CDN.
+    post_script: str or list or None (default None)
+        JavaScript snippet(s) to be included in the resulting div just after
+        plot creation.  The string(s) may include '{plot_id}' placeholders
+        that will then be replaced by the `id` of the div element that the
+        plotly.js figure is associated with.  One application for this script
+        is to install custom plotly.js event handlers.
+    full_html: bool (default True)
+        If True, produce a string containing a complete HTML document
+        starting with an <html> tag.  If False, produce a string containing
+        a single <div> element.
+    animation_opts: dict or None (default None)
+        dict of custom animation parameters to be passed to the function
+        Plotly.animate in Plotly.js. See
+        https://github.com/plotly/plotly.js/blob/master/src/plots/animation_attributes.js
+        for available options. Has no effect if the figure does not contain
+        frames, or auto_play is False.
+    default_width, default_height: number or str (default '100%')
+        The default figure width/height to use if the provided figure does not
+        specify its own layout.width/layout.height property.  May be
+        specified in pixels as an integer (e.g. 500), or as a css width style
+        string (e.g. '500px', '100%').
+    validate: bool (default True)
+        True if the figure should be validated before being converted to
+        JSON, False otherwise.
+    auto_open: bool (default True)
+        If True, open the saved file in a web browser after saving.
+        This argument only applies if `full_html` is True.
+    div_id: str (default None)
