Update to data visualization

As a passing note ... visualization of the data updated. Incorporated google spreadsheets to make it easier to update the data when new data is available, and to make it so multi0year data could be quickly assessed. But google spreadsheets don't embed well, and are difficult to view on smaller screens. Data has been updated to infographics that should be easy to view and read on any device. Hopefully these changes will make the data more accessible and easier to view and understand!
