Looking at What is New with InfoGraphics Lumira 1.22.1
You can see what is new in the help here: http://help.sap.com/businessobject/product_guides/vi01/en/lum_122_whatsnew_en.pdf
For InfoGraphics you can have the grid shown while you are building the story. Note the grid does not publish. It looks like the old graph paper.
In the above, you can set the scrolling to be continuous with the InfoGraphic.
In this example, I left it widescreen
When you create a new story there are new InfoGraphic Templates. I tried the Overview one here.
I look forward to learning more at BI 2015 in March.
