We'll close out 2022 and and share what you would like Charming Data to focus on in 2023. If you're interested in having your own Dash tutorial video highlighted on Charming data, I invite you to create and share them with me. Feel free to use this session to let me know what topics you would like to create videos on. ... https://www.youtube.com/watch?v=j8bMMCPyBTc

Learn to create the Sunburst Diagram in python to visualize hierarchical data. I'll share the source Code and link to data. The sunburst is often referred to as a radial tree map. Under 30 lines of code, and using Plotly Express, we will create multiple Sunbursts, change the styling, hover, color, and much more. Links Below...

In part 2 of Dash tutorial, we'll connect our CRUD App to PostgreSQL databases: one on our computer, and one online via Heroku. The database on the computer will allow you to test your database connection before deploying it to the web. The database on Heroku will allow others to use your dashboard app and save changes to the live.

Review to the app's layout to understand everything displayed on the page. In this tutorial series we'll create the front end interface in Python using Dash. We will use a pre-built smart contract, written in solidity, to create and deploy a decentralized application on top of it. There will be a little bit of javascript used for inserting data into the blockchain, but most of the app will be in Python. dApp in Python code: https://github.com/charmingdata/dApp-animal-shelter-python/tree/main Smart Contract: https://github.com/charmingdata/all-smart-contracts/blob/main/ShelterDB.sol Polygon zkEVM testnet: https://testnet-zkevm.polygonscan.com/address/0x1245dBd38a1FF2371436245A9D7eF7AE4A9a1A26 DBC Alert component: https://dash-bootstrap-components.opensource.faculty.ai/docs/components/alert/ DBC Radio Buttons component: https://dash-bootstrap-components.opensource.faculty.ai/docs/components/input/ DMC Loading-spinner component: https://www.dash-mantine-components.com/components/loadingoverlay Video layout: 00:00 - What you will learn 00:31 - Contrainer and Titles 01:18 - Alert Component 03:18 - First Row & Col components 04:31 - Input Field Component 06:05 - Radio Buttons 07:46 - Submit Button 09:25 - Second Row 11:02 - Get Shelter Information ***************************************************************************************** Join my channel to support its existence and access perks: https://www.youtube.com/channel/UCqBFsuAz41sqWcFjZkqmJqQ GitHub tutorials code: https://github.com/charmingdata?tab=repositories&q=&type=&language=&sort=name Connect with me on LinkedIn: https://www.linkedin.com/in/charmingdata/ ... https://www.youtube.com/watch?v=c67dq7ADWHw
