You're sitting in the CFO's chair at a fictional company. The dashboard is above; beside it, an agent that answers about what you're looking at — and draws whatever chart you ask for, from the real data.
The data is synthetic and the company doesn't exist. The dashboard and the agent read the SAME dataset: if they could disagree, the demo would fall apart on the first question. That's exactly what you should demand of a real dashboard.
In a real implementation these tools point at your systems, your repository and your data. Book 30 minutes and we'll go through your case.
