ChartGen.ai Documentation

ChartGen.ai is a free AI-powered chart generator that transforms your data into professional visualizations in seconds. You can create 9 different chart types including bar charts, line charts, pie charts, area charts, scatter plots, heatmaps, combo charts, waterfall charts, and funnel charts. Simply upload your CSV or Excel file, describe what you want in plain English, and the AI generates a beautiful chart instantly. No design or coding skills required.

Yes, ChartGen.ai is a core product capability of Ada.im, a comprehensive AI-powered data analysis platform. While ChartGen.ai focuses specifically on chart generation and data visualization, Ada.im offers a complete suite of data analysis tools including automated reports, interactive dashboards, presentation generation, SQL query assistance, and more. For advanced data analysis capabilities beyond chart generation, you can register for a free account at ada.im.

ChartGen.ai supports CSV files (.csv) and Excel files (.xlsx, .xls). You can also paste data directly from any spreadsheet application like Microsoft Excel, Google Sheets, or Apple Numbers. The maximum file size for uploads is 10MB, and our AI automatically detects column types, date formats, and numeric values to make chart creation seamless.

Our advanced AI uses natural language processing to understand your chart requirements. It analyzes your description along with your data structure to determine: 1) The most appropriate chart type, 2) Which fields to use for categories and values, 3) The best aggregation method (sum, average, count, etc.), 4) Meaningful data insights to highlight. You can be as specific or general as you like - saying 'show me sales by region' or 'create a horizontal bar chart showing Q4 2024 revenue by product category sorted descending' both work.

ChartGen.ai supports: 1) Bar Charts - for comparing categories, 2) Line Charts - for trends over time, 3) Pie Charts - for proportions and percentages, 4) Area Charts - for volume and cumulative data, 5) Scatter Plots - for correlations and relationships, 6) Heatmaps - for matrix patterns and density, 7) Combo Charts - for multiple metrics on dual axes, 8) Waterfall Charts - for sequential changes, 9) Funnel Charts - for conversion pipelines. Each type can be customized with different color themes and configurations.

The best chart type depends on what you want to communicate: Use Bar Charts for comparing categories or rankings. Use Line Charts for showing trends over time. Use Pie Charts for displaying parts of a whole (percentages). Use Area Charts to emphasize volume or cumulative totals. Use Scatter Plots to show correlations between two variables. Use Heatmaps for pattern recognition in matrix data. Use Combo Charts when comparing metrics with different scales. Use Waterfall Charts for financial breakdowns. Use Funnel Charts for conversion or pipeline analysis.

ChartGen.ai supports six aggregation methods: 1) Sum - adds all values together, ideal for totals. 2) Average - calculates the mean, good for typical values. 3) Count - counts the number of records. 4) Min - finds the smallest value. 5) Max - finds the largest value. 6) Count Distinct - counts unique values only. The AI automatically selects the most appropriate aggregation based on your data and request, but you can easily change it after chart generation.

Yes! ChartGen.ai offers 12 professional color themes inspired by leading consulting firms. Available themes include Navy Blue, Ocean Teal, Royal Purple, Emerald Green, Coral Pink, Sky Blue, Forest Green, Amber Orange, Rose Pink, Slate Gray, Indigo, and Midnight. You can select a theme before generation or use the built-in color picker to specify custom colors. The AI will apply your preferred palette consistently across all chart elements.

ChartGen.ai allows you to download charts as high-quality PNG images (2x resolution) for free. For additional export options including SVG (scalable vector graphics for editing and web embedding) and PDF (print-ready documents), you can access these features through Ada.im. All exports maintain professional quality suitable for presentations, reports, and publications.

Yes, data security is our top priority. Your uploaded files are processed in real-time and are not permanently stored on our servers. All data transmission is encrypted using HTTPS/TLS. We never share your data with third parties. ChartGen.ai is SOC 2 compliant, making it suitable for enterprise use with sensitive business data.

ChartGen.ai offers 50 free charts per month with access to all 9 chart types and 12 color themes. This is sufficient for most individual users and small teams. For unlimited chart generation, advanced export options, team collaboration features, and access to the full Ada.im data analysis suite, you can upgrade to a premium plan.

ChartGen.ai can process datasets up to 10MB (approximately 100,000+ rows depending on columns). For larger datasets, the AI intelligently samples and aggregates data to ensure optimal chart performance. If you need to work with massive datasets or require real-time database connections, Ada.im offers enterprise solutions with higher limits and direct database integration.

To create a multi-series chart, ensure your data has a category column and multiple value columns. For example, for 'Sales by Region by Year', have columns for Region, 2022 Sales, 2023 Sales, and 2024 Sales. Then describe your chart: 'Create a grouped bar chart showing sales by region for each year'. The AI will automatically detect multiple series and display them with different colors.

In 'Auto' mode, ChartGen.ai's AI analyzes your data and natural language description to automatically determine the best chart type. This is ideal when you're not sure which visualization would work best. If you select a specific chart type from the dropdown, the AI will generate that exact type regardless of the data structure. Use Auto for exploration and specific types when you have a clear visualization goal.

Yes! After generating a chart, you can: 1) Change the aggregation method (sum, average, count, etc.), 2) Switch to a different color theme, 3) Regenerate with a modified prompt, 4) Request different insights. For advanced editing capabilities like custom titles, axis labels, and annotations, these features are available through the full Ada.im platform.

ChartGen.ai automatically detects date columns in your data. For time-series visualizations: 1) Ensure your date column is properly formatted (YYYY-MM-DD, MM/DD/YYYY, etc.), 2) Include numeric value columns you want to visualize, 3) Describe your chart like 'Show monthly revenue trend for 2024'. The AI will parse dates, aggregate by appropriate time periods, and create line or area charts showing trends over time.

ChartGen.ai handles missing values intelligently: 1) Numeric nulls are excluded from aggregations (won't affect averages), 2) Empty category values are grouped as 'Unknown' or 'Other', 3) The AI may suggest data cleaning if significant missing data is detected. For best results, clean your data before uploading or specify how to handle missing values in your prompt.

ChartGen.ai is designed for professional use. The charts feature: 1) Clean, modern design suitable for executive presentations, 2) 12 professional color themes, 3) High-resolution PNG exports (2x), 4) Consistent styling across all chart types. Many users create charts in ChartGen.ai and paste them directly into PowerPoint, Google Slides, or Keynote presentations.

For comparison charts, structure your data with a category column and value columns for each item being compared. Example: For 'Product A vs Product B sales by month', have columns for Month, Product A Sales, and Product B Sales. Then say 'Compare Product A and Product B sales over time'. For side-by-side category comparisons, use grouped bar charts. For trend comparisons, use line charts with multiple series.

After generating a chart, ChartGen.ai provides AI-generated insights including: 1) Key trends and patterns in your data, 2) Notable outliers or anomalies, 3) Percentage changes and comparisons, 4) Statistical observations like highest/lowest values. These insights help you understand your data quickly and can be included when sharing charts with stakeholders.

ChartGen.ai offers API integration through Ada.im for workflow automation. You can: 1) Use the n8n workflow template for automated chart generation, 2) Integrate with Dify for AI-powered data visualization in your applications, 3) Access the REST API for custom integrations. Visit our Integrations page for setup guides and API documentation.

For funnel charts, structure your data with: 1) A 'Stage' column containing funnel stages in order (e.g., 'Visitors', 'Leads', 'Opportunities', 'Customers'), 2) A 'Value' column with the count or amount at each stage. Then describe: 'Create a sales funnel chart showing conversion stages'. The AI will display stages as progressively narrowing sections with conversion rates between stages.

ChartGen.ai is a focused, free tool for AI-powered chart generation - perfect for quickly creating individual visualizations.
