I have created a shiny application where it executes sql query and sends the output as dataframe to leaflet to display the graph. The execution time is taking longer than expected. So, I wanted to display a progress bar to let know the user of how long it takes to display the output. Any Idea on how to do this?
In order to show the percentage, I don't know on how long it takes to display the graph. So, any suggestion would be helpful.
