DashR vs. Dash with Python

I’m choosing whether to create my web application with dash in R or dash in python. My application will involve processing and plotting a lot of data so I was wondering if either R or python would be better for overall speed and performance and if the choice between these two languages even matters?

Assuming you’re language agnostic, generally R’s built-in dataframe has better performance than Python’s pandas dataframe. It will depend on your data transformations ultimately.
