Great content. Thanks for doing this Adam! Question, what’s the difference between instantiating a data frame first and then just have the callbacks work off of that vs using dcc store? Is the data frame re-fetched from the server on every callback?

I follow your videos and you are great in teaching.I just started with dash and also tableau.Can you make a video to compare these two technologies so I know to stick to which one:) At the time I know that tableau is much faster in building visualizations and much less coding is needed.But dash is more customizable and programming way of doing tasks...I dont know which one is better to choose,for a personal data science road map.

Hi Ali, you are correct in your assessment, comparing between Dash and tableau. It depends how you intend to use data visualization in your career. If you need something which and out-of-the-box dashboards, then tableau is good. But dash is open source and offers so much flexibility and customisation that is valuable for data scientists, especially those people that want to do a lot with their dashboard

Great explanation, is it possible to store multiple datasets in one callback, in that case once the dropdown selections are made you can immediately do the necessary steps on multiple tables in one callback. i.e. if you had to save the three datasets in this example independently (dataset1; dataset2; dataset3)

Hi everyone, Need some help, Trying to make a multipage app with a huge amount of tabs, the tabs need an input value from a button on a page, Stock/Crypto symbol button input box, then that symbol needs to be saved with ddc.store so when i click on one of the 20 tabs it keeps that symbol to use in the newly displayed tab? I cant get it to work, I have to re-click/re-enter the symbol into the input box every time i click on a new tab, I cant get the structure of the storage callback to work and then how to use that output into the tab callback.. Any help would be appreciated

Is it possible to create an app using dash and make it shareable only with employees on a company network? I want to create interactive plots that anyone within the company can access at anytime. Is there a way to do this using python-dash? Thanks!

Hi Sajith, that's possible. You can deploy on the intranet. I haven't done that but it's possible. Also you can deploy it to the web and use dash authentication to generate passwords that only your colleagues will know.

Does this cause a lot of network traffic? I would think the data has to be sent back to the server for all the other callbacks that are triggered by the updated Store data, but maybe I have a misunderstanding.

Hi. You can definitely share data with the DCC.store. but you need to make sure your data is a JSON type first, if you're going to use JSON.dumps
