I also wanted to create a more unopinionated vector library as far as whether methods should modify vectors in place or create new ones, since I found that most of the time I wanted a mix of both.

We'll start with a simple 2D dataset, which can be separated with a linear boundary. The data is plotted below, with "positive" examples indicated as "x" and "negative" examples indicated with "o".

The DWG format is the most common 2D CAD file format for engineers, but there are alternatives that may have their own advantages or disadvantages depending on the context and purpose of the design.
