Exploring Data with 3D Scatter Plot
3D plots add a third spatial dimension to a visualization, letting you encode an extra variable along the depth axis. CanvasXpress renders 3D bar graphs and 3D scatter plots that can be rotated and explored interactively, revealing structure and relationships that are hard to see in two dimensions. They are well suited to multivariate data where three quantitative axes tell the story together.
