#> Ĭheck out the "Usage Examples" section of our docs to see more. # Or create a diagram object that you can inspect and do stuff with You can also import the erdantic Python library and use its functions. The rendered format is interpreted from the filename extension. Simply specify the full dotted path to your data model class and an output path. The fastest way to produce a diagram like the above example is to use the erdantic CLI.
SQLITE ER DIAGRAM INSTALL
You can get the development version from GitHub with: pip install Then to install erdantic and its Python dependencies from PyPI: pip install erdantic Attribute in ER diagram can be represented by using the oval shapes but this further gets divided into the various form which we are going to. For recommended options and installation troubleshooting, see the pygraphviz docs. If not using conda, Graphviz must be installed first (before you can install pygraphviz). If you are on Linux or macOS, the easiest way to install everything together is to use conda and conda-forge: conda install erdantic -c conda-forge InstallationĮrdantic's graph modeling depends on pygraphviz and Graphviz, an open-source C library. Great for adding a simple and clean data model reference to your documentation. Docstrings are even accessible as tooltips for SVG outputs. dataclasses from the Python standard libraryįeatures include a convenient CLI, automatic native rendering in Jupyter notebooks, and easy extensibility to other data modeling frameworks.
Diagrams are rendered using the venerable Graphviz library. Erdantic is a simple tool for drawing entity relationship diagrams (ERDs) for Python data model classes.
