Thanks for the lesson Harshit, I learnt some cool stuff and thanks for leaving the little errors in, it's nice to see as a beginner that everyone gets errors.

[@panchammahto7837]

This is some real encouraging stuff🎉👍 I have been going through a lot of EDA work in recent time, but the static nature made it look bit boring. The amount of interactivity you brought into the jupyter notebook was amazing. Thank you!

[@elliott3165]

This is great stuff! Thank you for the tutorial. I’m going to totally start using this!

Hi Harshit, Great video. However, I was wondering if instead of downloading the data everytime we could web scrape the data and then make the dashboard so that it is live. I was trying to web scrape the covid 29 tracker of India but I am not able to figure out how to go about it. Can you help in this regard. Thanks a ton

[@mamtarajput4804]

nice explanation.

[@vijays7098]

Great video. How did you fix the formatting of your charts when running Voila?

[@DataSciencewithHarshit]

Voila require semicolon after plt.show(); that should do the trick for you. If it still doesn't work for you, I've added the GitHub link, you can check out the code there.

Hey! Thanks for the lesson it was very knowledgeable. But I have a doubt, can I know why does the final map using folium doesn't plot few of the countries as per the data?

Been a long time but I think it might be because of the location json file I'm feeding to the map.

Is voila supposed to render for a long time? If not, is there a solution to this or do you have a recommended substitute to voila?

[@DataSciencewithHarshit]

It should be done within 3-4 mins tops. If it's taking longer check the logs there must ne something for you to look over.

[@gowthamicherukuri5039]

Hi Harshit! I am supposed to create a button and when the button is clicked, an input box should appear that takes the user input. I created button using widgets.button. An then added onclick behavior to invoke another function which shows user text input. This is working fine when running in jupyter notebook but when I open using voila, I am not able to get the user input box when I clicked the button. Any suggestions?

[@DataSciencewithHarshit]

There are certain limitations to voila, I am not sure if the kind of interaction you want to develop is supported by voila. Even if it does ut should be using the right functions and layouts. Keep trying, I'll start a discord channel to discuss these dort of issues with others.

[@mohitshetty8535]

[@tejbhatt20]

DO we need to give citation to your github or channel if we put your code on github?Can we put this project on resume?

[@DataSciencewithHarshit]

I think you should try and build over this foundation and then you can put it in your resume. Pls do give due credit to the channel.

There are different ways to do that in general but you can configure your code to use foor loops or write functions or may be merge the files... Read about these and then check which one aligns with your end goal.
