# Build visuals with Generative BI
Build visuals

Quick authors can use the **Build a visual** button to build a custom visual that's generated from author input. The author's input uses natural language to describe the desired outcome for the new visual. You can enter a custom description, or you can choose from a list of generated suggestions that Amazon Q has generated for the topic that's attached to the analysis. The following image shows a custom visual that's created with the **Build a visual** menu.

**To build a visual with Generative BI**

1. Navigate to the analysis that you want to work in and choose **Ask to build a visual**.

1. In the **Build a visual** panel that appears, perform the following steps.

   1. Describe the data that you want to visualize. You can enter a custom description, or you can choose from the **Suggested** questions that are generated based on the analysis' data.

      When you describe the data that you want to visualize, you can phrase it as a question, or you can use conversational phrases or filters. For example, you can enter "How many people signed up for a free trial last month?" or "Free trial sign ups by month." Both statements generate a visual that shows the number of free trial sign-ups by month. You can also get responses to vague language or keyword style requests.

      Suggested questions can include a mix of artificial intelligence (AI) generated questions and human verified questions. Human verified questions appear with a check mark next to the suggestion.

   1. Choose **Build**.

   1. Review the visual that generates. To refine the data presented in the visual, enter a new description into the **Build** bar, and then choose **Build**. Use the forward and back arrows to review the changes made to the visual without losing any progress.

   1. When you're satisfied with the visual, choose **ADD TO ANALYSIS**.

1. Describe the calculation outcome that you want to achieve. For example, "year over year percent change in daily sales."

After you add a calculation to the expression editor, you must name the calculation before you can save it.
