A simple data structure visualizer for Jupyter Notebooks
Project description
dsvisualizer
A simple data structure visualizer for Jupyter Notebooks.
Usage
To visualize your linked list implementation import the library and add the corresponding decorators to the linked list node and container.
You can see an example notebook in introduction.
Installation
You can install using pip
:
pip install dsvisualizer
If using Google Colab
You need to run the following snippet to enable custom widgets.
from google.colab import output
output.enable_custom_widget_manager()
Development Installation
Create a dev environment:
conda create -n dsvisualizer-dev -c conda-forge nodejs yarn python jupyterlab
conda activate dsvisualizer-dev
Install the python. This will also build the TS package.
pip install -e ".[test, examples]"
When developing your extensions, you need to manually enable your extensions with the notebook or lab frontend. For Lab, this is done by the command:
jupyter labextension develop --overwrite .
yarn run build
For classic notebooks, you need to run:
jupyter nbextension install --sys-prefix --symlink --overwrite --py dsvisualizer
jupyter nbextension enable --sys-prefix --py dsvisualizer
Note that the --symlink
flag doesn't work on Windows, so you will here
have to run the install
command every time that you rebuild your extension.
For certain installations you might also need another flag instead of
--sys-prefix
, but we won't cover the meaning of those flags here.
How to see your changes
Typescript:
If you use JupyterLab to develop then you can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the widget.
# Watch the source directory in one terminal, automatically rebuilding when needed
yarn run watch
# Run JupyterLab in another terminal
jupyter lab
After a change wait for the build to finish and then refresh your browser and the changes should take effect.
Python:
If you make a change to the python code then you will need to restart the notebook kernel to have it take effect.
