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.

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.

What is a pie chart and when should I use one?

A pie chart is a circular visualization divided into slices that represent proportions of a whole. Each slice's size corresponds to its percentage of the total. Use pie charts when you want to show how parts make up a whole, compare relative sizes of categories, or display percentage distributions. They're ideal for data with 3-7 categories.

How do I create a pie chart with ChartGen.ai?

Creating a pie chart is simple: 1) Upload your data file (CSV, Excel, or JSON), 2) Select 'Pie Chart' from the chart types, 3) Describe what you want to visualize in natural language (e.g., 'Show budget distribution by department'), and 4) Click Generate. Our AI will automatically create a beautiful pie chart from your data.

What data formats work best for pie charts?

ChartGen.ai supports CSV, Excel (.xlsx, .xls), and JSON files. For pie charts, your data should have a category column (labels for each slice) and a numeric column (values that will be converted to proportions). The AI automatically calculates percentages and creates the visualization.

What's the difference between a pie chart and a donut chart?

A donut chart is a pie chart with a hollow center. Both display proportional data, but donut charts have a blank space in the middle that can display a total value or key metric. Donut charts are often considered more modern and can be easier to read. ChartGen.ai can create both styles.

How many slices should a pie chart have?

For optimal readability, pie charts work best with 3-7 slices. Too many slices make it difficult to compare proportions. If you have more categories, consider grouping smaller ones into an 'Other' category, or use a bar chart instead. ChartGen.ai can automatically suggest the best approach for your data.

Can I customize the colors of my pie chart slices?

Yes! You can choose from 12 pre-designed color themes or use the color picker to create custom palettes. You can also specify color preferences in your prompt (e.g., 'use company brand colors' or 'blue color scheme'). The AI will apply harmonious colors that make your chart visually appealing.

How do I add labels and percentages to my pie chart?

By default, ChartGen.ai adds labels with category names and percentages to your pie chart. You can customize this in your prompt—request 'show only percentages', 'add value labels', or 'include a legend'. The AI intelligently positions labels to avoid overlap.

Is ChartGen.ai part of Ada.im?

Yes! ChartGen.ai is a core product capability of Ada.im, an AI-powered data analysis platform. While ChartGen.ai focuses on chart generation, Ada.im offers additional features like data connectors, team collaboration, interactive dashboards, and automated reporting.

Can I create an exploded pie chart to highlight a specific slice?

Yes, you can create exploded pie charts where one or more slices are separated from the center for emphasis. Simply mention in your prompt which slice you want to highlight (e.g., 'explode the largest segment' or 'separate the Marketing slice'). This is great for drawing attention to key data points.
