TikZ & Graphics

How to Import GeoGebra or Inkscape Drawings into TikZ

Drawing complex geometric constructions or detailed illustrations directly in TikZ code can be tedious. GeoGebra and Inkscape offer visual drawing environments that can export TikZ/PGF code, giving you the best of both worlds — visual design with LaTeX-quality output. This guide shows you how to get clean, editable TikZ code from both tools. Bibby AI accepts TikZ code from any source and renders it instantly, making the import-and-refine workflow much faster than on Overleaf.

Export from GeoGebra to TikZ

GeoGebra has built-in TikZ/PGF export. Create your construction visually, then export the code:

% In GeoGebra Desktop:
% 1. Create your geometric construction
% 2. File → Export → Graphics View as PGF/TikZ
% 3. Copy the generated code into your LaTeX document

% The exported code looks like this (simplified example):
\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[line cap=round, line join=round, >=triangle 45,
    x=1.0cm, y=1.0cm]
    % GeoGebra exported code (cleaned up)
    \draw[thick] (0,0) -- (4,0) -- (2,3.46) -- cycle;  % Triangle
    \draw[dashed] (2,0) -- (2,3.46);  % Altitude
    \draw (2,1.15) circle (1.15cm);   % Inscribed circle

    % Labels
    \node[below left] at (0,0) {$A$};
    \node[below right] at (4,0) {$B$};
    \node[above] at (2,3.46) {$C$};
    \node[below] at (2,0) {$H$};
\end{tikzpicture}
\end{document}

% Tip: GeoGebra's export is verbose — clean up redundant styles and
% round coordinates to make the code more maintainable.

Export from Inkscape to TikZ

Use Inkscape's 'Save As' PGF/TikZ output or the svg2tikz extension to convert SVG drawings:

% Method 1: Inkscape built-in export
% 1. Create or open your drawing in Inkscape
% 2. File → Save As → choose 'PGF/TikZ (*.tex)'
% 3. Import the result in your document

% Method 2: Use the svg2tikz extension (better output)
% Install: pip install svg2tikz
% Convert: svg2tikz input.svg > output.tex

% Method 3: Include Inkscape SVG with overlay technique
\documentclass{article}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{import}

% For Inkscape's 'PDF + LaTeX' export (best for math labels):
% In Inkscape: File → Save As → PDF → check 'PDF+LaTeX'
% This creates two files: drawing.pdf (graphics) and drawing.pdf_tex (labels)

\begin{document}
\begin{figure}[h]
    \centering
    \def\svgwidth{0.8\textwidth}
    \import{./figures/}{drawing.pdf_tex}  % Imports both PDF and labels
    \caption{Diagram with LaTeX-rendered math labels.}
\end{figure}
\end{document}

Clean Up and Optimize Imported TikZ Code

Exported code is often verbose. Here's how to clean it up for maintainability:

% BEFORE: Raw GeoGebra/Inkscape export (verbose)
% \draw [line width=1.2pt, color=blue] (1.9999999,0.0000001) -- (4.0000002,0.0000001);
% \draw [line width=1.2pt, color=blue] (4.0000002,0.0000001) -- (2.9999998,2.9999999);

% AFTER: Cleaned up and readable
\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[
    thick, blue,  % Apply common styles once
]
    % Rounded coordinates, meaningful names
    \coordinate (A) at (2, 0);
    \coordinate (B) at (4, 0);
    \coordinate (C) at (3, 3);

    \draw (A) -- (B) -- (C) -- cycle;

    % Add labels (often missing from exports)
    \foreach \point/\pos in {A/below, B/below, C/above}
        \node[\pos] at (\point) {$\point$};
\end{tikzpicture}
\end{document}

% Cleanup checklist:
% 1. Round coordinates to 1-2 decimal places
% 2. Name coordinates with \coordinate for readability
% 3. Extract common styles to tikzpicture options
% 4. Remove redundant draw options
% 5. Add meaningful labels

💡 Tips

•GeoGebra's TikZ export rounds poorly — always clean up coordinates manually for readable code.
•Inkscape's PDF+LaTeX export is the gold standard for figures with math: graphics stay as PDF vectors, labels render in LaTeX.
•The svg2tikz Python tool often produces cleaner output than Inkscape's built-in PGF export.
•After importing, define \coordinate names for key points — this makes the diagram much easier to edit later.
