Hi there. I just downloaded this TBAnnotaionClustering sample and have two question .

First: Can the sample be modified to request the .csv file from google sheets for example(or any other webser as .sjon) ? How should that be implemented ? The original Hotels.csv file have 6.4MB, I think its kind of heavy to download. But in my project would be significant less points and we will increase the locations over time.

Second: What would be the code like to display that Info button in callouts, marker annotations ? I would like to launch for each marker its website to open in Safari ?

Thanks and excellent sample, will study it!
