Frequently asked questions
Which packages does the generated code need?
Load tikz with the positioning, shapes.geometric and arrows.meta libraries. If you generate a function plot, also load pgfplots and set \pgfplotsset{compat=1.18}. The page shows the exact preamble for the diagram you are building.
Does it work in Overleaf?
Yes. Copy the TikZ code into your document body and add the preamble lines. If a diagram does not compile, check that the libraries listed above are loaded and that your pgfplots version is recent.
Can I get the picture as well as the code?
Yes. You can copy the live preview as SVG and paste it into a vector editor, in addition to copying the TikZ.
Is my diagram saved?
Your work stays in the page while it is open and is not uploaded. Copy the code to keep it.
