Data Visualization Services

Recharts (and similar libraries Nivo, Victory, Chart.js) are React component libraries they provide pre-built chart types (bar, line, area, scatter) as composable React components that consume data via props. They are the right choice for standard business charts in React applications fast to implement, well-documented, and maintained. D3.js is a low-level data visualisation library it binds data to SVG elements and provides the building blocks (scales, axes, layouts) to construct any possible visualisation. Use D3 when no pre-built chart library has the chart type you need (network graphs, Sankey diagrams, custom geospatial charts, animated data stories). BI tools (Metabase, Looker, Tableau) are drag-and-drop tools for non-developers they are fast for standard charts but cannot produce custom interactive chart experiences or integrate deeply with a React product's design system. ClickMasters uses Recharts/Nivo for product-embedded standard charts, D3.js for custom chart types, and BI tools for internal analytics.

SVG (Scalable Vector Graphics) is the default for most charts: each element is a DOM node (hoverable, interactive, accessible, easy to style with CSS), renders sharply at any resolution, and is the output format of D3.js and most React chart libraries. Use canvas rendering when: the chart has more than 10,000-50,000 data points (SVG performance degrades significantly each data point is a DOM node, and 100,000 DOM nodes make the browser sluggish), real-time updates at 60fps are required (canvas redraws are faster than DOM mutations), or WebGL rendering is needed for 3D or GPU-accelerated visualisation (Deck.gl uses WebGL for millions-of-points geospatial visualisations). ECharts (Apache) and Vega-Lite support automatic switching between SVG and canvas based on data size. ClickMasters uses SVG for standard business charts and canvas/WebGL for high-volume or high-performance visualisation requirements.
