Chart anatomy title insight table
chart-anatomy-title-insight-table
Required anatomy: title (timeframe + unit) + insight summary + data table. Subtitle or callout, not both. Summary states what the data means (“requests rose from 220 to 420”), not “the line goes up.” Small datasets: full semantic table visible, not behind a toggle. Medium: summarised table. Large: summary + download of source.
Description
Required anatomy: title with timeframe and unit, insight summary stating what the data means, and a data table. Use subtitle or callout, not both. Small datasets show a full semantic table visible, not behind a toggle. Pass when those hold. Fail when there is no table for a small set (or only behind a toggle), the summary is “the line goes up,” or the title omits unit or timeframe.
When to use
Publishing charts that need scannable anatomy and accessible data.
Not when
Missing tables for small sets, vague summaries, or titles without unit or timeframe.
Agent hint
Require timeframe-plus-unit title, meaningful insight, and a visible table for small sets.
Title includes timeframe + unit; insight says what the data means; small sets show a visible semantic table; subtitle and callout are not both used.
No table for a small set (or table only behind a toggle); summary is “the line goes up”; title omits unit/timeframe.
