What types of charts can I create with ChartGen.ai?

ChartGen.ai supports 9 professional chart types: Bar Charts (vertical and horizontal), Line Charts, Pie Charts, Area Charts, Scatter Plots, Heatmaps, Combo Charts (bar + line), Waterfall Charts, and Funnel Charts. Each chart can be customized with 12 professional color themes.

What file formats does ChartGen.ai support?

ChartGen.ai supports CSV files (.csv) and Excel files (.xlsx, .xls). You can also paste data directly into the interface. The AI automatically detects column types, dates, and numeric values to make chart creation seamless.

How does ChartGen.ai compare to Excel charts?

ChartGen.ai is faster and easier than Excel for creating charts. While Excel requires manual chart configuration and formula knowledge, ChartGen.ai uses AI to automatically select the best chart type, configure axes, and apply professional styling. You can create a publication-ready chart in seconds versus minutes with Excel.

How does ChartGen.ai compare to Tableau?

ChartGen.ai is a free, instant alternative to Tableau for simple chart creation. While Tableau is a powerful enterprise BI platform requiring licenses and training, ChartGen.ai offers zero learning curve and instant results. It's perfect for quick visualizations without the complexity of dashboard setup.

Is my data secure when using ChartGen.ai?

Yes, data security is a top priority. Your uploaded files are processed in real-time and are not permanently stored on servers. All data transmission is encrypted using HTTPS, and ChartGen.ai is SOC 2 compliant for enterprise use. Your data is never shared with third parties.

What is the best chart type for comparing data?

Bar charts are the best chart type for comparing values across categories. Use horizontal bar charts when category names are long, and vertical bar charts for time-based comparisons. ChartGen.ai's AI can automatically recommend the best chart type based on your data structure.

What chart should I use to show trends over time?

Line charts are ideal for showing trends over time and continuous data changes. Use area charts if you want to emphasize volume or cumulative totals. ChartGen.ai can create both types and will recommend the best option based on your data.

When should I use a pie chart?

Use pie charts to show part-to-whole relationships when you have 2-5 categories that sum to 100%. Avoid pie charts for more than 7 categories or when comparing similar values. ChartGen.ai will suggest alternatives like bar charts if your data isn't suitable for pie charts.
