I am unable to visualize the data by giving an external link as a param to chart-studio.plotly.com. It redirects me to the same old plot.ly domain.
By visiting this site: https://chart-studio.plotly.com/external?url=https://raw.githubusercontent.com/plotly/datasets/master/iris.csv
redirects me to: Importing Data into Chart Studio Cloud
Please comment whether if the service is down or there is any other way to go about it. Thanks
