- [Audio to Waveform Video](https://elysiatools.com/en/tools/audio-to-waveform-video): Create a video from audio with a waveform visualization
- [Audio Visualizer Player](https://elysiatools.com/en/tools/audio-visualizer-player): Play audio files with real-time frequency visualization
- [Bar Chart Generator](https://elysiatools.com/en/tools/bar-chart-generator): Generate customizable bar charts from data with various styling options
- [Box Plot Generator](https://elysiatools.com/en/tools/box-plot-generator): Generate box plots for statistical distribution analysis with quartiles, whiskers, and outliers
- [Bubble Chart Generator](https://elysiatools.com/en/tools/bubble-chart-generator): Generate customizable bubble charts from data with three dimensions (x, y, size)
- [子弹图生成器](https://elysiatools.com/en/tools/bullet-chart): 目标vs实际对比图表，包含目标线、实际值、比较范围
- [Calendar Heatmap Generator](https://elysiatools.com/en/tools/calendar-heatmap): Generate GitHub-style calendar heatmaps to visualize activity patterns over time, perfect for tracking yearly contributions, habits, or metrics
- [Central Limit Theorem Demonstrator](https://elysiatools.com/en/tools/central-limit-theorem-demonstrator): See the Central Limit Theorem in action: draw samples from a non-normal source distribution (uniform, exponential, Poisson, or Bernoulli), plot the histogram of sample means, and overlay the predicted Normal curve N(μ, σ²/n). Compare empirical vs theoretical mean and standard error, and watch convergence tighten as the sample size grows.
- [Chord Diagram Generator](https://elysiatools.com/en/tools/chord-diagram-generator): Generate interactive chord diagrams for visualizing bidirectional flows and relationships between entities
- [Comparison Bar Chart Generator](https://elysiatools.com/en/tools/comparison-bar-chart): Generate back-to-back bar charts for positive and negative value comparison, perfect for contrasting data sets
- [Correlation Analyzer](https://elysiatools.com/en/tools/correlation-analyzer): Advanced correlation analysis tool that calculates correlation coefficients between variables to measure the strength and direction of their linear relationships. Perfect for statistical analysis, financial modeling, scientific research, and data exploration. Features: - Multiple correlation methods (Pearson, Spearman, Kendall) - Correlation matrix generation - Statistical significance testing (p-values) - Confidence intervals calculation - Heatmap visualization - Scatter plot matrix generation - Missing value handling strategies - Outlier detection and handling - Group analysis capabilities - Detailed statistical reports Common Use Cases: - Financial market analysis and risk assessment - Scientific research and hypothesis testing - Customer behavior and marketing analysis - Healthcare and medical data analysis - Quality control and process optimization - Educational performance evaluation
- [Min-Max Normalizer](https://elysiatools.com/en/tools/data-normalizer-minmax): Normalize numerical data using Min-Max scaling to transform values to a 0-1 range. Perfect for machine learning preprocessing, data analysis, and feature scaling. Features: - Min-Max scaling (0-1 normalization) - Custom range support (e.g., -1 to 1) - Multiple column selection - Automatic data type detection - Handles missing values - Preserves non-numeric columns - Statistical summary included Common Use Cases: - Machine learning feature preparation - Neural network input normalization - Data visualization preprocessing - Comparative analysis across different scales
- [Donut Chart Generator](https://elysiatools.com/en/tools/donut-chart-generator): Generate customizable donut charts (ring charts) from data with various styling options, perfect for showing proportions with a central space
- [Doppler Effect Calculator (Frequency Shift)](https://elysiatools.com/en/tools/doppler-effect-calculator): Compute observed frequency and frequency shift for a moving source and/or observer
- [ECharts Theme Token Extractor](https://elysiatools.com/en/tools/echarts-theme-token-extractor): Extract design tokens — colors, numbers, font sizes and strings — from an ECharts theme JSON and export them straight into your design system. Paste a theme object (the kind registered via echarts.init(dom, themeName)) and the tool walks every leaf, tagging each color (with optional named/rgb → hex normalization), spacing number, font size and string, then emits clean CSS variables, a Tailwind theme.extend config, Style Dictionary tokens.json, or SCSS variables. Bridges the gap between an ECharts visualization theme and Figma/CSS/Tailwind design tokens without copying each value by hand.
- [Venn Diagram Generator](https://elysiatools.com/en/tools/euler-diagram-generator): Generate customizable Venn diagrams to visualize set relationships, intersections, exclusions, and hierarchical structures
- [Flowchart Maker](https://elysiatools.com/en/tools/flowchart-maker): Describe nodes and connections in Mermaid-style syntax and generate a layered flowchart diagram
