Features

• Heatmap Visualization - Provides a library to create visual representations of data density on a canvas.
• Canvas Rendering - Utilizes direct pixel manipulation on an HTML5 canvas to render high-performance density maps.
• Data-to-Pixel Coordinate Transforms - Translates abstract data coordinates into specific pixel offsets to accurately place heat intensity markers.
• Data Visualization Libraries - Provides a set of tools for drawing dynamic graphical representations of datasets directly in the browser.
• Heatmap Renderers - Generates density-based color overlays using weighted points to visualize data distribution.
• HTML5 Canvas Libraries - Functions as a JavaScript library specifically designed for rendering 2D density visualizations using the HTML5 Canvas API.
• Data Visualization Tools - Provides a tool for transforming raw data into graphical representations of intensity using color gradients.
• Heatmap Visualizations - Creates visual overlays representing the concentration and intensity of data points on web pages.
• Geospatial Mapping - Represents the concentration of events or objects across a coordinate system or map interface.
• Radial Gradient Overlays - Uses circular gradient overlays at each data point to simulate heat intensity and organic blending.
• Color Lookup Tables - Maps grayscale intensity values to a predefined color palette using a transition table to generate the heat effect.
• Color Blending - Implements additive color blending to represent increasing data density through shifts in color.
• User Behavioral Mapping - Maps user click patterns and interaction hotspots to analyze and improve interface design.
• Offscreen Rendering - Renders density maps to a hidden offscreen canvas before transferring the final result to the visible screen.
• Game Engines - Canvas-based library for generating heatmaps.
