In the current version of SandDance during an animated transition, all data points begin animating simultaneously. We now support the ability to customize the order in which each datapoint transitions between views. We call these staggered transitions.
Support for background images
You can now use an image as the background of a Scatterplot or Stacks chart to help provide additional context to the visualization.
This example is a Scatterplot showing house sales data for King County, WA.
This example is a Stacks plot of the positions of shots made on a basketball court by Kobe Bryant, who was a professional basketball player for the Los Angeles Lakers team.
New rendering engine
We’ve completely re-engineered our WebGL rendering engine. It has two modes:
- Standard mode can handle many data points while still being responsive and works on mobile devices and lower power GPUs .
- Enhanced 3D mode adds shadows, emissive lighting, and depth of field effects, and requires a more powerful GPU.
The rendering engine also now supports stereo rendering and immersive Virtual Reality experiences using WebXR.
The following examples compare the two rendering modes. In each image, the same visualization is shown using both the standard rendering mode (top half) and enhanced 3D rendering mode (bottom half).
Shadows can be used to help convey depth in 3D visualizations, such as in the following examples.
Emissive lighting can be used to emphasize selections, such as in the following examples.
Depth of field can also be used to emphasize and draw attention to specific areas of 3D visualizations, such as in the following examples.
Adaptive 3D chart axes
In a 3D view, axes now adapt to the viewing angle, ensuring they are always visible without obscuring the data:
New selection modes
As well as using the axis edge divisions and labels, you can now also make selections via the axes background grid squares:
We have also now added lasso selection, using the ALT key with a mouse drag:
