[Tex/LaTex] How to get mathematical fonts to Illustrator

fontsgraphicsillustratorsymbols

I am doing a thesis on graph theory, and I am currently drawing graphs with Illustrator. Vertexes and edges are easy to draw, but how about naming them? How do I get the symbols in image look like symbols in the text?

I totally, totally feel your pain.

When I was writing my dissertation on string theory I encountered the same issue. I managed to develop a pipeline which seems to work quite well:

Draw your graphs/images in Illustrator.
Use http://latex2png.com/. Type your latex equation in there, then preview at 2000 dpi.
Save the image, then load into Illustrator. Alternatively, you can speed things up by using a screencapture software (e.g. ShareX) so you can skip the image saving+loading process.
When in Illustrator, select your imported equation image and choose Object --> Image Trace --> Make and Expand. It is very important to obtain a high dpi image for this step to work favorably.
Your equation should now be a vector graphic.
Select your new vector graphic equation and choose Object --> Ungroup. This will separate the white spaces in your equation from the black content that you need.
Select the white spaces and delete them.
You now have a fully editable equation looking exactly like it does in Latex. You can scale/adjust and colour to your requirements.

Using these same steps, I have managed to create things like in the images below:

Hope that helps,

Code:

\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
    xmin=-1, xmax=2,
    ymin=-1, ymax=2,
    axis lines=center,
    axis on top=true,
    domain=0:1,
    ]

    \addplot [mark=none,draw=red,ultra thick] {1-x};
\end{axis}
\end{tikzpicture}
\end{document}

Alternatively you could do this just in tikz:

enter image description here

Code:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
    \draw [thin, gray, ->] (0,-1) -- (0,2)      % draw y-axis line
        node [above, black] {$y$};              % add label for y-axis
    
    \draw [thin, gray, ->] (-1,0) -- (2,0)      % draw x-axis line
        node [right, black] {$x$};              % add label for x-axis
    
    \draw [draw=red,ultra thick] (0,1) -- (1,0);% draw the graph

    \node [left] at (0,1) {$1$};                % label y-intercept
    \node [below] at (1,0) {$1$};               % label x-intercept
\end{tikzpicture}
\end{document}
