Question 1

What do I actually receive after purchasing?

Accepted Answer

You get access to copy the Vega JSON specification directly from this page. Type your column names, choose the colours and labels, then paste the specification into Ataytis Vega Studio inside Power BI Desktop and add the same columns to the visual’s Values field well.

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 specification.

Question 3

Does this one need data, unlike your other visuals?

Accepted Answer

Yes, and it is the one thing to understand before buying. Most of the AtaytisTech Library is self-contained — the content is set on the product page and travels inside the specification. Circle Pack is different: it charts your model, so it needs columns in the visual’s Values field well. What it does not need is any editing of the JSON.

Question 4

How do I tell it which columns to use?

Accepted Answer

You type the column names on this page, exactly as Power BI displays them, and they are written into the specification for you. If a column is renamed later, the names sit in four clearly marked places at the very top of the specification rather than scattered through it.

Question 5

What happens if a column name does not match?

Accepted Answer

The circles will not draw, because there is nothing to group or size by. Check the name against the Data table in the Studio, including capitals, spaces and punctuation — Power BI display names are matched exactly.

Question 6

How much data can it handle?

Accepted Answer

Ataytis Vega Studio receives up to 10,000 rows, but readability runs out long before that. Every distinct combination of your levels becomes a circle, and a few hundred circles is already a mosaic rather than a chart. Aggregate to the level you actually want to show, and use the deepest level for the detail worth clicking into.

Question 7

Is my data sent to AtaytisTech to draw the preview?

Accepted Answer

No. The preview on this page runs on sample figures of ours, so you can see your styling and layout without uploading anything. Your own data is only ever read inside Power BI, by a Microsoft-certified visual that makes no external calls.

Question 8

Can I use this in client reports or commercially?

Accepted Answer

Yes. Once purchased, you can use the visual in any report for personal or commercial use, against any data. You may not resell or redistribute the raw JSON specification itself.
