Generic class for any type of marker that is placed on a specific
location on a plot.
The shape of the marker is defined by the subclass that is used.
All markers have an edge line, a size, and a fill color.
The size of the Marker should be an integer. This is a generalized
diameter-type size, in pixels.

Property Possible Values Description
====================== ================= =======
color | Color The color of the edge line.
| Color format
fillcolor | Color The color of the center of the marker.
| Color format
width int (1) The width of the edge line.
style | 'solid' The edge line style.
| 'dash'
| 'dot'
| 'dashdot'
| 'dashdotdot'
cap | 'square' How the end of the edge line should be drawn.
