Diving deeper into edge options

Every edge operation builds its own path; that’s why edge supports general path options. Furthermore, an edge can have connection-specific options, such as defining a straight line or a curve.

So, we can divide edge styling options into the following:

• Path options, including general TikZ options
• Connection options

Let’s look at them separately.

Path options

Remember, a path is a series of lines or curves with nodes and other elements. All options that you can set to a path, you can set to an edge, such as line style options.

These options can be as follows, using example values for clarity instead of syntax grammar formality:

• color=red: This draws the edge in a red color
• ultra thin, very thin, thin, semi thick, very thick, ultra thick: These options define the thickness of the edge line
• line width=3pt: This denotes that the edge shall have a thickness of 3 pt
• loosely dotted, dotted, densely...
