@bchen39 It looks like it's down, but it was working before. If you didn't delete it, it might have gotten cleaned up automatically.

A few notes from brief testing:

• Add a paragraph under the title to provide some context for each of the datasets. It's hard to understand what each one describes
• Some of the columns don't make sense without context (Walc, etc.). Might be clearer to re-phrase these or just delete them
• Changing the axes via the dropdown didn't reload the graphs (couldn't verify since the app went down)

@bryannho Please check my latest version. I made sure the title of each graph explains what they are, and cleaned up data that do not make sense. The app should work properly now. Let me know in case the app gets cleaned up again and I can redeploy.

@bchen39 let's use the prod environment from now on for the demo apps

[bryannho]

@bchen39 it got cleaned up, please deploy on prod and resend the link. @edublancas I think he'll need a pro account since it's a docker app, can he use the contact@ploomber.io one?

[edublancas]

@bchen39 DM me your prod account via Slack so I upgrade it.

@bryannho I think let's use separate accounts so we have better control, I'll manually keep an eye on the apps to shut down the ones we're not using

[bchen39]

@bryannho link to app on prod environment. This should work now.

Looks great!

minor comments regarding secrets. ensure to mention this in the blog post: that people should use our secrets feature

also, since the db credentials have been disclosed publicly, ensure you change the db authentication details

[edublancas]

@bryannho please help me checking the comments from my existing review and approve if you think it's good to go now

Please try deploying the app using the Dash framework instead of Docker. Once you get it working u can remove the Dockerfile. Also, do share the new app link @bchen39
