Produces a semiotic square visualization.

    Parameters
    ----------
    semiotic_square : SemioticSquare
        The basis of the visualization
    x_label : str
        The x-axis label in the scatter plot.  Relationship between `category_a` and `category_b`.
    y_label
        The y-axis label in the scatter plot.  Relationship neutral term and complex term.
    category_name : str or None
        Name of category to use.  Defaults to category_a.
    not_category_name : str or None
        Name of everything that isn't in category.  Defaults to category_b.
    neutral_category_name : str or None
        Name of neutral set of data.  Defaults to "Neutral".
    num_terms_semiotic_square : int or None
        10 by default. Number of terms to show in semiotic square.
    get_tooltip_content : str or None
        Defaults to tooltip showing z-scores on both axes.
    x_axis_values : list, default None
        Value-labels to show on x-axis. [-2.58, -1.96, 0, 1.96, 2.58] is the default
    y_axis_values : list, default None
        Value-labels to show on y-axis. [-2.58, -1.96, 0, 1.96, 2.58] is the default
    color_func : str, default None
        Javascript function to control color of a point.  Function takes a parameter
        which is a dictionary entry produced by `ScatterChartExplorer.to_dict` and
        returns a string. Defaults to RdYlBl on x-axis, and varying saturation on y-axis.
    axis_scaler : lambda, default scale_neg_1_to_1_with_zero_mean_abs_max
        Scale values to fit axis
    Remaining arguments are from `produce_scattertext_explorer`.

    Returns
    -------
        str, html of visualization
