This bug is probably more general and also appears in other widgets: set color to a different attribute than shape. You get this.

add circle and points around add circle points labels fix Inputs/Outputs data validation aspect ratio = 1 (circle, not ellipse) commit selection and selection groups hide axis fix divide max attrs, displayed box height use old point on the circle move points on a circle fix commit icon added do not show main axis when there is no data script fix filter on mouse hover larger circle point labels fix view box clear fix

| Radviz ([1]_) is a neat non-linear multi-dimensional visualization | ||
| technique that can display data on three or more attributes in a 2-dimensional | ||
| projection. The visualized attributes are presented as anchor points equally |

| physics: each point is held in place with springs that are attached at the | ||
| other end to the attribute anchors. The stiffness of each spring is | ||
| proportional to the value of the corresponding attribute and the point ends up |
| other end to the attribute anchors. The stiffness of each spring is | ||
| proportional to the value of the corresponding attribute and the point ends up | ||
| at the position where the spring forces are in equilibrium. Prior to | ||
| visualization, attribute values are scaled to lie between 0 and 1. Data |

The extra sentence can IMO be omitted, if not add it separately (otherwise hard to read).

Issue
Radviz widget wanted. Radviz widget is available in Orange 2 but not in Orange 3.
Description of changes
New widget in Orange 3. This is much simpler widget than one in Orange 2. Radviz in Orange2 has too many settings.
