Hi Javier, thanks for your question! There isn't a feature to export the default dashboard as-is. You can, however, create a Custom Report that is every bit as visual as the one in the dashboard.
To get started, go to your dashboard. Click on the "Custom Reports" button, located underneath the main navigation bar on the RH side of the page. Then follow the directions to create your report using the easy-peasy, drag and drop interface. You can make the report look like your dashboard, or you can customize it to your heart is content.
When you've finished putting the report together, you will be given the option to print a PDF. After you create your PDF, you can then schedule the report to be automatically generated and emailed to you on the schedule that works best for you. Voila!
I hope that helps. Let me know if you have questions. 
Christy
While it is not as clear-cut as to weather this is a ranking factor as is the case for page load time, Google is measuring it and they are all about rewarding websites that provide a great user experience, right?
