Dot Plot Generator

This data visualization tool creates interactive dot plot charts for statistical analysis and data presentation. Users input data points manually, paste CSV data, or select from preset sample datasets including student scores, sales trends, and temperature comparisons. The canvas-based rendering engine draws each data point as a customizable dot with configurable style, color, and size options.

The chart customization panel offers dot styles (circle, square, diamond, triangle), color palettes (modern, classic, pastel, ocean, earth), and size controls ranging from 4 to 20 pixels. Grid line toggles and axis label inputs allow precise chart formatting for professional presentations. The real-time preview updates instantly as users modify any parameter, enabling rapid iteration on chart design.

Export functionality generates high-resolution PNG images suitable for reports, presentations, or academic papers. The tool calculates optimal axis ranges automatically from input data while allowing manual override for specific visualization requirements. All rendering occurs client-side using HTML5 Canvas, ensuring data privacy and instant responsiveness.
