Open-source demos hosted on Dash Gallery

Last update: Jan 7, 2023

Overview

Dash Sample Apps

This repository hosts the code for over 100 open-source Dash apps written in Python or R. They can serve as a starting point for your own Dash app, as a learning tool to better understand how Dash works, as a reusable templates, and much more.

Most apps in this repository are hosted on Dash Gallery, which is our internal server running on Dash Enterprise Kubernetes. Note that you can find both open-sourced apps and demos for our licensed products, including Design Kit and Snapshot Engine. If you are interested in learning more, don't hesitate to reach out to get a demo. If you want to only see the open-sourced apps, select the "Open Source" tag.

Downloading and running a single app

Visit the releases page and download and unzip the app you want. Then cd into the app directory and install its dependencies in a virtual environment in the following way:

python -m venv venv
source venv/bin/activate  # Windows: \venv\scripts\activate
pip install -r requirements.txt

then you can run the app:

python app.py

Cloning this whole repository

To clone this repository, run:

git clone https://github.com/plotly/dash-sample-apps

Note this might take a long time since it copies over 100 apps available in the repo. If you just want to try one app, refer to the section above.

App pull request

[X] This is a new app

Playground deployment URL (new version): https://dash-playground.plotly.host/dash-label-properties

Old Python app repository link: https://github.com/plotly/canvas-portal/blob/master/apps/object-properties/app.py

Workflow

[X] I have created a branch in the appropriate monorepo, and the elements necessary for successful deployment are in place.

[X] If the app is a redesigned and/or restyled version of an existing gallery app, I've summarized the changes requested in the appropriate Streambed issue and confirm that they have been applied.

[X] If the app is on the Dash Gallery portal, I have added a link to the GitHub repository for the source code in the portal description.

[ ] If the app is a reimplementation of a Python gallery app for the DashR gallery, the app in this PR mimics, as closely as possible, the style and functionality of the existing app.=

[X] I have removed all Google Analytics code from the app's assets/ folder.

The pre-review review

I have addressed all of the following questions:

[x] Does everything in my code serve some purpose? (I have removed any dead and/or irrelevant code.)

[x] Does everything in my code have a clear purpose? (My code is readable and, where it isn't, it has been commented appropriately.)]

[x] Am I reinventing the wheel? (I have used appropriate packages to lessen the volume of code that needs to be maintained.)

analytics: remove Google Analytics in favor of Google Tag Manager

As per conversation here: https://github.com/plotly/marketing-team/issues/118#issuecomment-542334742

We'd like to put the Google Tag Manager script into our dash-sample-apps instead of using GA only.

GTM includes such tracking codes like Pardot, which the marketing team would find useful to add on the apps.

Paste this code as high in the <head> of the page as possible:

<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-N6T2RXG');</script>
<!-- End Google Tag Manager -->

Additionally, paste this code immediately after the opening <body> tag:

<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-N6T2RXG"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>

In trainable segmentation, it is very slow to add annotations after a first segmentation has been performed

App name

https://dash-gallery.plotly.host/dash-image-segmentation/

Description of bug

After an initial segmentation has been performed, one often wishes to add new annotations to correct the model, but the loading component seems to be spinning forever and it is not possible to add new annotations. Unchecking "Show segmentation" does not seem to solve the problem.

Tagging you here @nicholas-esterer, I can also take a look after we decide together on priorities for the CZI apps.

Ideally it should not take more time to add new annotations than before the segmentation has been computed.
