I'm using this website to draw graphs: http://madebyevan.com/fsm/

My graph is supposed to look like this:

The website creates the suitable LaTeX code which I put in my document:

begincenter
begintikzpicture[scale=0.2]
tikzstyleevery node+=[inner sep=0pt]
draw [black] (18.04,-17.02) circle (3);
draw (18.04,-17.02) node $q_1$;
draw [black] (8.7,-15.7) -- (15.07,-16.6);
fill [black] (15.07,-16.6) -- (14.35,-15.99) -- (14.21,-16.98);
endtikzpicture
endcenter

But rather when I compile my document, it only shows the node's text, without the circle or arrow:

• 
  

  I did use the following in the document's preamble:

  
  
  

  usepackagetikz

  
  



• I write my documents in LyX.



• The code above works for my peers who tried it. (works = outputs the expected graph)

Thanks in advance!

I can get the desired output with your code. Therefore there might be a problem with your LyX or your TikZ.

However, why do you have to go to external websites? when your code can be as simple as this?

documentclass[tikz]standalone
usetikzlibraryarrows.meta
begindocument
begintikzpicture
node[circle,draw,minimum size=1cm] (a) $q_1$; % A node bounded by a circle of diameter 1cm
draw[Triangle-] (a)--++(-2,.4); % Draw an arrow to the node
endtikzpicture
enddocument
