• Clean headers help. Clear column names give Chartchooser a better read on your data.
• Be specific about your goal. “Show the trend” and “compare regions” lead to different charts.
• Ask for a dashboard if you have several metrics to show together.
• Iterate freely. Ask for a different chart type, colors, or layout until it fits.

Set it up once, and turning any dataset into the right chart takes just a few clicks.
