Thank you for the clarification! It's not exactly a "dot matrix" because the dots aren't on a grid, but I think that would be a much better summary. Also a better summary than "series of dots".

The algorithm, which generates a set of discrete XY coordinates, is the interesting part of this page.
Changing the size and color of the dots yields no new information about the operation of the algorithm. The dots are just a way to visualize the coordinates on a plane.

This may be hair-splitting, but when I say dot I mean a mathematical point. Of course it does not matter how we represent a zero-dimensional object in a graphical scene (we need some kind of representation, obviously).
My point was the emphasis on "XY coordinates". It is just a suggestion to be more precise here.

The reason I made this was indeed to get Cartesian coordinates. I needed them to intersperse dot images between data-driven dot arrangements, like in this example: https://bl.ocks.org/alizauf/de25f00bf369010b265362e3e53d6629
The animations interpolate the dots between different XY coordinates.
For me as a scientist "XY coordinates" most likely means cartesian coordinates. In SVG (like virtually any other graphics file format), coordinates are given in a cartesian coordinate system by default.
However, what is meant here is: "Turning an SVG into a dot matrix" or "Turning SVG paths into a series of dots".
The purpose of the author is mainly to emphasize clarity of animations.
