class Dots

Dots draws SVG symbols at a set of points.

Arguments

• Dots(d, symbol, width, height, attribute=value)*

	d		_*required*_		list of (x,y) points
	symbol		_default_=None		SVG symbol or a new identifier to label an auto-generated symbol; if None, use pre-defined `circular_dot`
	width, height		_default_=1, 1		width and height of the symbols in SVG coordinates
	attribute=value pairs		_keyword list_		SVG attributes

Note that a list of (x,y) points can be constructed with Python's `zip` function. This can be useful for constructing `d`.

>>> x = [1,2,3,4,5]
>>> y = [1,4,9,16,25]
>>> zip(x,y)
[(1, 1), (2, 4), (3, 9), (4, 16), (5, 25)]

The `symbol` can be a new SVG object constructed like this

>>> SVG("symbol", SVG("circle", cx=0, cy=0, r=1, stroke="none", fill="black"), viewBox="0 0 1 1", overflow="visible", id="new_identifier")

or using the [DefMake_symbol make_symbol] function. You can also just supply a new identifier, and Dots will call [DefMake_symbol make_symbol] for you.

You need to supply an identifier that hasn't already been used in your SVG image, so that the dots link to the right reference.

SVG method

Dots has an *SVG* method, as described in [GeneralPrimitive General features for all primitives].
