jdaviz
is a package of astronomical data analysis visualization tools based on the Jupyter platform. It is one tool that is a part of STScI's larger Data Analysis Tools Ecosystem. These GUI-based tools link data
visualization and interactive analysis. They are designed to work
within a Jupyter notebook cell, as a standalone desktop application,
or as embedded windows within a website -- all with nearly-identical
user interfaces. jdaviz
is under active development, and users who
encounter bugs in existing features are encouraged to open issues in this
repository.
jdaviz
provides data viewers and analysis plugins that can be flexibly
combined as desired to create interactive applications that fit your workflow.
Three named preset configurations for common use cases are provided. Specviz
is a tool for visualization and quick-look analysis of 1D astronomical spectra.
MOSviz is a visualization tool for many astronomical spectra,
typically the output of a multi-object spectrograph (e.g., JWST
NIRSpec), and includes viewers for 1D and 2D spectra as well as
contextual information like on-sky views of the spectrograph slit.
Cubeviz provides a view of spectroscopic data cubes (like those to be
produced by JWST MIRI), along with 1D spectra extracted from the cube.
Imviz provides visualization and quick-look analysis for 2D astronomical
images.
This tool is designed with instrument modes from the James Webb Space Telescope (JWST) in mind, but the tool should be flexible enough to read in data from many astronomical telescopes. The documentation provides a complete table of all supported modes.
For details on installing and using JDAViz, see the Jdaviz documentation.
If you uncover any issues or bugs, you can open a GitHub issue if they are not already reported. For faster responses, however, we encourage you to submit a JWST Help Desk Ticket.

We love contributions! jdaviz is open source, built on open source, and we'd love to have you hang out in our community.
Imposter syndrome disclaimer: We want your help. No, really.
There may be a little voice inside your head that is telling you that you're not ready to be an open source contributor; that your skills aren't nearly good enough to contribute. What could you possibly offer a project like this one?
We assure you - the little voice in your head is wrong. If you can write code at all, you can contribute code to open source. Contributing to open source projects is a fantastic way to advance one's coding skills. Writing perfect code isn't the measure of a good developer (that would disqualify all of us!); it's trying to create something, making mistakes, and learning from those mistakes. That's how we all improve, and we are happy to help others learn.
Being an open source contributor doesn't just mean writing code, either. You can help out by writing documentation, tests, or even giving feedback about the project (and yes - that includes giving feedback about the contribution process). Some of these contributions may be the most valuable to the project as a whole, because you're coming to the project with fresh eyes, so you can see the errors and assumptions that seasoned contributors have glossed over.
Note: This disclaimer was originally written by Adrienne Lowe for a PyCon talk, and was adapted by jdaviz based on its use in the README file for the MetPy project.
