Hi, I have three related articles for you today. You may have seen the first one but the second was published today. All are concerned with creating web data visualizations using Plotly and Flask. The first article is a couple of weeks old and compares the construction of simple dashboards with Dash and how it is easier and more flexible to make them using Plotly and Flask.
The second one goes further by introducing interactivity that is implemented with callbacks in Dash, but again only using Plotly and Flask.
Finally, for those who are not familiar with Flask, I have written a simple intro.
I hope that they are useful and that you enjoy reading.
