Is the word "radial" in proper usage if I want to describe a star-like structure?

I want to describe a star-like structure as shown in the following figure. In the figure, the center object is surrounded by a number of other objects, and there are rays pointing from the center point to the surrounding objects.

Figure 1

The idea is that the center object can be represented by the set of the surrounding objects due to similar appearance.

I want to name this structure as a Radial Representation of the center object. Is word radial in appropriate usage? (I am writing a technical paper, and I want give this structure a proper name.)

• What is the subject of the paper? Physics? Electronics? Computing? etc. This may be important if a pre-existing term is available. Alternatively, I might suggest: "Star representation" or "Orbital representation", but this does have the connotation that the external nodes are moving. Oct 21, 2013 at 15:44
• This is related to image processing. The center image is a weighted sum of the surrounding images. There isn't a pre-existing term. I want to give it a name that makes it stand out. Oct 22, 2013 at 4:11
• @JamesWebster "Orbital" to me would suggest that the outer nodes are arranged in rings. Dec 6, 2017 at 2:42

• On the other hand, radial 'drainage' is somewhat like the diagram mentioned by OTP. And even a google search of 'radial' shows such diagrams. :) Oct 20, 2013 at 5:30
• I think an earlier term was 'spider diagram'. Oct 20, 2013 at 13:12
• What is the proper way of describing the structure as shown in Figure 1? One thing I forgot to mention, this is not a network as in the phrase "communication network". Describing it as a network is not appropriate here. Oct 21, 2013 at 15:18
• stellate? resembling a star.

...the center object is surrounded by a number of other objects, and there are rays pointing from the center point to the surrounding objects.

sounds very similar to the dictionary definition of radial:

a radial pattern or design consists of straight lines that all go out from the center of a circle

So a describing the figure as a radial representation would be entirely appropriate.
