d3jsThe Humble SVG <rect>: When a Rectangle Beats a Div, a Path, and a Canvas
Why the SVG <rect> element is often the sharpest, simplest tool for badges, chart bars, and outlines — with a worked example, crisp-edge fixes, and honest limits.
rectScripting Inkscape's CLI: Batch SVG Export in a Build Pipeline
Generate PNG and PDF assets from committed SVG sources using Inkscape's CLI actions in CI — with a multi-density export example, version-pinning advice, and the font-substitution trap to avoid.
inkscapeUsing SVGO's prefixIds Plugin to Prevent ID Collisions in Inline SVGs
Inline SVGs share one global ID namespace, so duplicate ids collide. SVGO's prefixIds plugin rewrites ids and their internal references with a per-file prefix — here's the config, the ordering pitfall, and how to verify it.
svgoDevicon: Font Classes or Raw SVGs? Picking the Right Integration for Your Stack
Devicon ships every logo as both an icon font and raw SVGs. Here's how to choose between them, with a worked skills-row example, bundle-size and accessibility trade-offs, and quick verification steps.
D3.js Data Joins with selection.join(): A Practical Render Pattern
Build a robust D3.js render loop using selection.join() with keyed data joins. Covers enter/update/exit handling, transitions, and a reusable render(data) pattern that avoids common bugs.
javascriptMaster Inkscape Live Path Effects: Pattern‑Along‑Path & Non‑Destructive Editing
Inkscape’s Live Path Effects let you apply pattern‑along‑path and other deformations non‑destructively. Follow a step‑by‑step example, see how the effects are stored in SVG, and learn the trade‑offs for performance and export fidelity.
Mastering Dynamic Updates with the D3.js .join() Pattern
The D3 .join() method turns the fiddly enter-update-exit lifecycle into one declaration. Learn how keyed data joins keep dynamic SVG charts in sync, with a worked animated scatter plot example.
Batch-Exporting SVGs with Inkscape's Headless CLI: Actions, DPI, and CI Pitfalls
How to use Inkscape's headless CLI to batch-export and normalize SVGs in scripts and CI: export arguments, the actions system, DPI vs pixel sizing, 0.9x migration, and the quoting, font, and latency pitfalls that bite in practice.
