12 JavaScript Data Visualizations
Explore the deep end of JavaScript Data Visualization by focusing on native and custom rendering. This guide walks you through building everything from standard bar charts to complex network graphs and 3D models. You’ll master techniques for handling time-series and geospatial data using pure JavaScript, with a strong emphasis on extensibility - allowing you to create unique, fully customizable visualization components beyond the limits of standard library templates.

Simple SVG Circle Graph with Animation
A smooth radial progress animation where the SVG stroke fills the circumference based on a dynamically calculated offset.
Incrementing Counter
A dynamic and engaging statistics block that creates a sense of activity and popularity through running numbers and background animation.
Goal Progress
A React-based goal tracker component that visually contrasts actual progress against a target pace using layered bars and dynamic status colors.
Motion Blurred Number Counter
As the slider moves, the numbers change rapidly, blurring horizontally to create a sensation of high-speed motion (motion blur), reminiscent of an old speedometer or a slot machine counter.
Serpentine Timeline Chart
This serpentine Gantt chart implementation leverages amCharts’ specialized SerpentineChart and CurveColumnSeries to visualize project timelines along a curved axis. JavaScript orchestrates multiple bullet types for event markers while CSS properties like strokeDasharray create the distinctive dashed guideline aesthetic, resulting in an elegant spiral timeline with interactive tooltips and smooth animations.
Centennial Timeline with Google Sheets
A demonstration of the TimelineJS library - a ready-made solution for creating interactive timelines where all content is loaded dynamically from a public Google Sheet, separating data from presentation.
Animated D3.js Pie Chart with Elastic Easing
This dynamic D3.js pie chart utilizes a custom elastic easing and a rotate transform for the spectacular “spin-in” animation of each slice.
Animated Pie Chart (V2)
A demo showcasing an adaptive, unique “ring” pie chart design using SVG circles, where each segment is animated and colored from a predefined JavaScript array.
Glitch Equalizer with Web Audio API and Canvas
This is a powerful demonstration of the Web Audio API and Canvas synchronization, where an AnalyserNode processes real-time audio data to dynamically drive complex visual glitch effects and an animated equalizer display.
Animated Periodic Table
This interactive demo uses pure JavaScript and D3.js to generate and animate a full Periodic Table via SVG, showcasing advanced techniques for data-driven element positioning and cyclical motion effects.
Thermometer with Animation
Elegant CSS showcase of an animated thermometer with dynamic temperature updates via JavaScript, supporting a dual Celsius/Fahrenheit scale and automatic Dark Mode theme.
D3 Line Marker Chart
A powerful D3.js line chart dynamically visualizes data aggregated from a nested JavaScript object, showcasing the use of reduce for data processing and scaleBand with scaleLinear for precise axis scaling.
