Agent Skills: visual-explainer

Generate self-contained HTML pages that visually explain systems, data stories, investigations, editorial workflows, and code changes. Use when the user asks for diagrams, architecture views, visual diffs, data tables, timelines, source maps, or any structured visualization that would be painful to read as terminal output. Also activates for tables with 4+ rows or 3+ columns. Adapted from nicobailon/visual-explainer with journalism, newsroom, and academic design sensibilities.
