Loading message for plotly graphs

[ucg8j]

The feature would be great to improve UI/UX. Particular with many shiny applications taking longer than 0.5 seconds to load. plotly.js does this, but the R implementation does not.

Reproducible example
This issue is reproducible across any R implementation of plotly. It's documented on Stackoverflow and the r plotly community:
http://stackoverflow.com/questions/36129522/show-loading-graph-message-in-plotly
https://community.plot.ly/t/how-to-show-loading-graphs-message-in-plotly/684

@cpsievert - BTW, thank you so for your work on R plotly, your impact is huge.

Hi,

I have created a Shiny module (https://github.com/andrewsali/plotlyBars
) that wraps the mentioned stackoverflow solution in a way that the loading animation automatically shows / hides depending on whether the plotly plot should be drawn.

Once you install it from github, it's a very simple and small change to call the module to create the plot that already has the loading animation.

A runnable example is also given on the github page.

Cheers,

Andras
