Cosmic Data Stories are online interactive resources for teaching the public data science skills. They are built on research-grade visualization tools like glue and WorldWide Telescope.

This repository is a monorepo for the Cosmic Data Stories project. It contains the code for the Cosmic Data Stories website, as well as the code for the individual stories.

To install a data story, clone or download this repository and navigate to the story directory. Note: it is recommended to install the stories in a virtual environment to avoid conflicts with other packages.

# Example install for Hubble's Law
cd cosmicds/packages/cds-hubble
pip install uv
uv pip install .

Developer setup is done using uv, a Python package and project manager. To get started, follow these steps:

1. Follow the uv installation instructions to install uv.
2. If you use conda or have an active conda environment, it is recommended you disable it as uv will create its own environment. You can do this by running:

   conda deactivate

   conda's auto-activation feature can also be disabled by running:

    conda config --set auto_activate_base false

   which will ensure that the conda base environment is not automatically activated when initiating a new terminal session.
3. Move to the top-level directory of the repository and run the following command to create a new uv environment:

   cd cosmicds
   uv sync --all-packages

   A new environment should now be defined in the .venv directory.
4. Activate the environment:

   source .venv/bin/activate

   This environment can be referenced in your editor of choice by setting the interpreter to .venv/bin/python.

All data stories should now be accessible by the command line. To start a story, run the following command:

<environment variables> solara run <story>.pages
