Oracle DV enables Freeform layout for Visualizations canvases, allowing users to exactly set the position of each element, and overlay visualizations one on top another.
Using Freeform layout, it becomes easy to compose custom infographics, with background images overlaid by interactive visualizations showing insights on underlying data. All in a meaningful, optimized overall layout representation.
Use the free example available on the Public-store (search for ID:60811A on left search dialog). You can deploy it in seconds on your own Oracle DV to see how it's built.
