Question 1

What do I actually receive after purchasing?

Accepted Answer

You get access to copy the Vega JSON spec directly from this page. Set up your names, mode and colours with the controls, then paste the spec into Ataytis Vega Studio inside Power BI Desktop. Everything travels inside the spec, so there is nothing else to set up.

Question 2

What is Ataytis Vega Studio?

Accepted Answer

Ataytis Vega Studio is our free, Microsoft-certified Power BI visual for rendering Vega specifications inside your reports. Install it once from Microsoft Marketplace in Power BI Desktop, then paste in any spec.

Question 3

Is it really random, or is the result baked into the spec?

Accepted Answer

Really random. The draw uses Vega’s random function, which runs in the browser at the instant somebody clicks the visual. Nothing is precomputed. You can paste the same spec into two reports and they will draw different names, and there is nothing in the JSON that could tell anyone the answer in advance.

Question 4

Can it draw from my data instead of a fixed list?

Accepted Answer

No — the names are set when you copy the spec. Ataytis Vega Studio is Microsoft-certified, which is what lets it be installed in locked-down tenants, and the entries travel inside the specification rather than being read from a field. In practice a standup roster or a prize-draw list changes rarely enough that editing it here and pasting again is quicker than wiring up a table.

Question 5

How many names can the wheel hold?

Accepted Answer

Up to twenty. Past about a dozen the segments get too thin to label at a readable size, so the page warns you when your names no longer fit and tells you what to change — a bigger visual, smaller labels, or fewer names.

Question 6

Does everybody looking at the report see the same result?

Accepted Answer

No. Each person’s copy of the report draws on their own click, so this is for a shared screen or a call where one person spins and everyone watches — which is how these things are used anyway. It is not a way to publish one agreed random result to an audience.

Question 7

Can I use it for a prize draw or a raffle?

Accepted Answer

For anything informal, yes. For a draw with real prizes and rules attached, remember that each viewer draws independently and nothing is recorded — there is no audit trail, so it is entertainment rather than evidence.

Question 8

Will it work in Power BI Service and on mobile?

Accepted Answer

Yes. It is an ordinary Vega spec with no external calls, so it renders the same in Power BI Desktop, in the Service and in the mobile apps. The draw is triggered by a click or a tap anywhere on the visual.
