Data Visualization 12.2.3 ( aka v3 ) is now downloadable from here
What a great upgrade it is, absolutely packed with new enhancements to increase the functionality and make data discovery even quicker.
The trendlines (as shown above) now allow for additional functionality such as a %age confidence.
There's new data sources too - we can even connect to BI Applications subject areas as well as analysis and folders.
There's even enhancements in the dataflow so we can perform more manipulation of the data as we load it
I'd do a demo of all the features, but Oracle have already done that in a nice little video suite which you can find here - which shows an overview and then some specifics - all of which are worth watching.
If you've any questions, please don't hesitate to contact us.
