For some reason, I could never get Richard Zach’s Ptolemaic Astronomy diagrams to work correctly, so I set out to write my own macros for TikZ that would allow me to draw Lewis system of sphere diagrams like these: These aren’t perfect by any means, but they are a decent first start. As far asContinue reading “Drawing Lewis Spheres in Tikz”

## Boolean Diagrams in TikZ

If you’re like me, you like representing philosophical ideas with intersecting circles. Here’s how to draw them in TikZ. Basics Circles and rectangles with rounded corners are easy: \draw[-] (0,0) circle (1cm);\draw[-,rounded corners,thick] (2,-1) rectangle (5,1); In addition to specifying coordinates absolutely, as we have been doing so far, you can also do so viaContinue reading “Boolean Diagrams in TikZ”

## Causal Modeling Diagrams in TikZ

Here, I’ll walk through how to code causal modeling diagrams in TikZ, like the following: TikZ is a package for LaTeX that is included in the base distribution. If you’re not sure what LaTeX is, or would like some help installing and getting started with it, I recommend AJ Hildrebrand’s site. Once you’re set upContinue reading “Causal Modeling Diagrams in TikZ”
