Plot a collection of geometries to `ax`. Parameters 'linewidth', 'linestyle', 'edgecolor',
'facecolor', 'color', 'marker', 'markersize' are used to describe the style of plotted figure.
For geometry types `Polygon` and `MultiPolygon`, only 'linewidth', 'linestyle', 'edgecolor',
'facecolor' are effective.
For geometry types `Linestring` and `MultiLinestring`, only 'color', 'linewidth', 'linestyle' are effective.
For geometry types `Point` and `MultiPoint`, only 'color', 'marker', 'markersize' are effective.
:type ax: matplotlib.axes.Axes
:param ax: The axes where geometries will be plotted.
:type geoms: Series or DataFrame
:param geoms: sequence of geometries.
:type linewidth: list(float)
:param linewidth: The width of line, the default value is 1.0.
:type linestyle: list(string)
:param linestyle: The style of the line， the default value is '-'.
:type edgecolor: list(string)
:param edgecolor: The edge color of the geometry, the default value is 'black'.
:type facecolor: list(string)
