In this PowerDataChat tutorial, we show how to create a bar chart from sales data using a simple natural-language question. Instead of manually building charts in Excel, creating pivot tables, or writing code, you can upload your Excel or CSV file and ask PowerDataChat to visualize the data for you. In this demo, we ask PowerDataChat to show total sales by product category as a bar chart and explain which category performed best. This tutorial is useful for anyone who wants to quickly understand business data, compare categories, and create clear visualizations without technical work. With PowerDataChat, you can: - Upload Excel or CSV files - Ask questions in plain language - Create bar charts and other visualizations - Get explanations together with charts - Continue asking follow-up questions - Download charts or export the full analysis as a report
