Title has_title
A chart-level title that anchors the takeaway in one phrase.
The cheapest way to tell the reader what the chart is doing. A good title doesn't describe the chart ("Revenue by quarter") — it states the takeaway ("Revenue grew 75% CAGR from $32M to $296M"). The slide title can carry this role; if it does, the chart-level title can be optional.
When critical
When the chart sits without a strong slide-level title carrying the takeaway, OR when the chart is shown out of context (in a report, in an embedded image).
When optional
When the slide title already states the takeaway in concrete terms.
Failures when missing
- hero-with-no-takeaway
- reader has to infer the so-what from axis labels alone
Failures when present (badly)
- descriptive-only title ("Q4 results") — wastes the slot
- too long — title becomes a paragraph
Critical for families
- bar
- time-series
- distribution
- specialized
