title: How to create picture/diagram from text?
body: <p>I'm trying to create a number of diagrams to be published online on my web site, as PNG images. I don't want to use any image editor like Photoshop or similar. Instead, I'd like to use some plaintext format and a compiler. The only tool I know so far is Graphviz/DOT, which has certain drawbacks. What are the alternatives?</p>
