Visualizing Multidimensional Covid-19 Data
DataVisio is a 3D software engine for immersive and interactive complex data visualizations on big screens, designed to generate a Data Experience. It is a B2B platform aimed at presenting specific business logic to customers, or deep abstract knowledge insights to educate the general public. Its main power is the capability of mapping complex data schemas to abstract visual nodes, edges and surfaces in 3D space, and the easy, "game" like, navigation into that space.
Covid-19 data (from the beginning of 2020) are rendered on different spaces, an abstract 3D space, over 2D Earth maps and a simulated 3D Earth environment. All data are projected on one, or more big immersive screens in front of a computer base station which contains the computer running the software. Covid-19 data -in geographic, temporal or a multitude of other dimensions- are displayed as points, or graph bars over locations. The exhibition visitor can fly in any of those spaces in real time performance using a gamepad controller on the base station. This allows him to navigate freely to any location of interest, examining at the same time the data displayed. Using the same gamepad it is also possible to change the time period of the rendered data and so explore, or even animate, their evolution in time. Additional information in the specified time can be retrieved by looking at a specific data point (an action which "selects" it).
Alternative modes of navigation using a Leap Motion Controller or a Kinect Sensor are possible, and more projector screens to increase the field of view and the immersion experience can be installed. A proposed large installation uses the detection of position and movement of exhibition visitors' faces as an input interface for navigation. Multiple detected faces and the "social distance" between them, behave similarity to multi-touch screen interfaces, changing the zoom factor of the current view.
Multidimensional abstract 3D projections
Visualizing the two waves of Covid-19 per country, arranged according to Geographic Latitude.
Visualizing multiple waves of Covid-19 represented in new deaths (7-day average) per million per country. The colors represent the effective reproduction rate (red R > 1.4, green R < 0.6). World data, till 26 March, 2021.

Geo globe projections
Seasonal variation of the 2 waves of Covid-19, represented in new cases (7-day average) per million, per country and the varying Sun illumination angle as the seasons progress (Winter is darker in the Northern Hemisphere because the Sun is lower on the horizon).

"There is a magic in graphs. The profile of a curve reveals in a flash a whole situation - the life history of an epidemic, a panic, or an era of prosperity. The curve informs the mind, awakens the imagination, convinces." Henry D. Hubbard.
