Professional Chart Generator Online — Powerful Data Visualization

Our advanced chart generator is a comprehensive solution for creating professional diagrams, function graphs, and data visualizations of any complexity. The tool combines ease of use with powerful customization options, enabling world-class chart creation for education, business, science, and media.

Wide Range of Chart Types

Line charts for trend analysis: line charts are the primary tool for displaying metric changes over time. Our generator supports both simple single-series line charts and complex multi-line diagrams with multiple datasets. Features include line style customization, markers, colors, and the ability to add trend lines and forecasts.

Bar charts and histograms: bar charts are ideal for comparing categories or data groups. The generator allows creating vertical and horizontal bars, grouped and stacked charts. Various display styles are supported, including 3D effects, gradients, and column appearance animations.

Pie charts and donuts: pie charts are indispensable for displaying structure and proportions. Our tool creates classic pie charts, donut charts, and semi-circular charts with the ability to highlight sectors, add labels in percentages or absolute values, and customize color schemes.

Scatter plots for correlation analysis: scatter plots are used to identify relationships between two variables. The generator supports creating scatter diagrams with trend lines, point clustering by categories, and customizing marker sizes and colors based on a third variable (bubble charts).

Area charts: area charts combine the advantages of line charts with the clarity of filled areas. Especially useful for displaying cumulative metrics, investment portfolios, and energy consumption by source. Regular, stacked, and normalized area charts are supported.

Mathematical functions: a specialized mode for plotting mathematical functions y = f(x). Trigonometric, logarithmic, power functions, and polynomials of any order are supported. Capability for parametric equations, polar coordinates, and complex functions.

Flexible Data Input Methods

Interactive table editor: the built-in editor allows quick data entry and editing directly in the browser. Support for copy-paste from Excel, series autofill, sorting, and data filtering. Real-time data validation with hints for error correction.

File uploads: support for popular file formats includes CSV, TSV, Excel (XLSX, XLS) with automatic encoding and delimiter detection. Intelligent data type recognition (numbers, dates, text) with manual adjustment options. Data preview before chart creation.

Mathematical parser: a powerful math expression parser supports standard mathematical functions (sin, cos, tan, log, ln, exp, sqrt), constants (pi, e), arithmetic operations, and parentheses. Ability to define parameters and variables for creating parametric graphs.

Professional Customization Options

Color schemes and themes: a large collection of professional color palettes, including schemes adapted for color-blind users. Ability to create custom color schemes and save corporate brand colors. Support for gradients, textures, and patterns.

Typography and labels: a wide selection of fonts, including web-safe and Google Fonts. Size, style, and color settings for all chart text elements. Support for HTML formatting in labels, mathematical symbols, and special characters.
