''' Display a variety of simple scatter marker shapes whose attributes
can be associated with data columns from
:class:`~bokeh.models.sources.ColumnDataSource` objects.

.. warning::
    The individual marker classes in this module are **deprecated since Bokeh
    2.3.0.** Please replace all occurrences of ``Marker`` models with
    :class:`~bokeh.models.glyphs.Scatter` glyphs. For example: instead of
    ``Asterisk()``, use ``Scatter(marker="asterisk")``.

    For backwards compatibility, all markers in this module currently link to
    their respective replacements using the
    :class:`~bokeh.models.glyphs.Scatter` glyph.

By definition, all markers accept the following set of properties:

* ``x``, ``y`` position
* ``size`` in pixels
* ``line``, ``fill``, and ``hatch`` properties
* ``angle``

The ``asterisk``, ``cross``, ``dash``, ``dot``, ``x``, and ``y`` only render
line components. Those markers ignore any values that are passed to the ``fill``
and ``hatch`` properties.

.. note::
    When you draw ``circle`` markers with ``Scatter``, you can only assign a
    size in |screen units| (by passing a number of pixels to the ``size``
    property). In case you want to define the radius of circles in
    |data units|, use the :class:`~bokeh.models.glyphs.Circle` glyph instead
    of the ``Scatter`` glyph.
