About This Tool

Need to visualize some data but don't want to mess with chart libraries? This tool generates common chart types—bar, line, pie, area, scatter—just by entering your data. Paste CSV or JSON, pick your chart type, customize colors and labels, export as an image. Great for quick presentations or reports when you don't need full-blown chart software.

Technical Details

Supports bar charts (vertical/horizontal), line charts, pie charts, area charts, scatter plots, and doughnut charts. Data input: CSV (comma-separated values) or JSON array. Customization: colors, fonts, title, axis labels, legend. Export as PNG or SVG. Responsive design—charts scale to container width. Uses Canvas API for rendering.

Algorithm

Data parsing: CSV/JSON to JavaScript array. Chart rendering: map data values to visual elements. Bar charts: rectangle heights based on values. Line charts: connect points with lines. Pie charts: arc sizes based on value proportions. Scaling: auto-calculates min/max values and scales accordingly. Colors assigned automatically or manually. Legend generated from data labels.
