Data Chart

Render measured data as static charts in the editorial figure language: bold sans title top-left, chip legend with uppercase mono labels, gridless ink axes, one accent family per page. SVG is the primary artifact (text preserved as text); a PNG proof render is mandatory before claiming success.

Routing: chart or diagram?

Decide by the figure's content, not its name:

• Measured data - real numbers, many points, true scales (log axes, distributions, time series) - this skill.
• Structure - boxes, arrows, layers, pipelines, or a few illustrative values inside a larger schematic - the sibling drawio-diagram skill, which shares the same visual tokens.
• Borderline (3-8 bars): real measurements that may change → this skill (the chart regenerates from data); a decorative sketch inside a diagram → drawio-diagram.
