d3-node

Offloads data processing and rendering to the server, reducing client-side load and improving performance, as emphasized in the README's rationale for pre-rendering and network overhead reduction.

Embeds CSS styles directly within SVG elements using the embedded stylesheets feature, ensuring self-contained graphics that are easy to share and integrate, demonstrated in the inline styles example.

Allows seamless adaptation of existing D3 examples from sources like bl.ocks.org for server-side use, leveraging familiar code patterns without major rewrites, as highlighted in the README.

Supports both SVG and Canvas outputs, with integration to node-canvas for generating PNG images, providing versatility in rendering formats for different use cases, shown in the canvas creation example.
