Lead with insight, then let the chart do the supporting work. Annotate what matters, add context where confusion starts, and pace the narrative for decisions.
What should the chart title do in a data story?
state the key takeaway, not the chart type
use an internal file name
repeat the y‑axis label
list the data source only
When is it better to use text instead of a chart?
when labels are unavailable
when you have one or two numbers that don’t benefit from visual encoding
whenever the dataset is large
when you want to impress with graphics
Which annotation approach best supports comprehension?
collect all notes in a separate legend
hide notes in the chart footer
place concise notes directly on the relevant marks
use long paragraphs above the chart
What kind of context most reliably prevents misinterpretation?
using ambiguous shorthand
moving context to a separate slide
omitting axes for a cleaner look
timeframes, definitions, and units stated near the chart
For comparisons across categories on mobile, which pattern often improves readability?
small multiples or stacked cards with per‑chart takeaways
3D area charts
one dense chart with tiny labels
rotated text at 90 degrees
What’s a good first edit when a bar chart feels cluttered?
switch to 3D bars
remove non‑essential ink and label only what helps the point
add gradients and heavy drop shadows
increase all gridline weights
If the audience is skeptical, what element can build trust fastest?
more vibrant colors
a larger company logo
a clear source line and a note on how the data was processed
an abstract illustration
Which title best suits a decision‑making audience?
the date of the meeting only
a vague question
the name of the dataset
a recommendation or action framed by the insight
When labels are long and categorical, which orientation usually helps?
horizontal bars with left‑aligned labels
vertical bars with 45° labels
sankey diagrams by default
3D pie charts
What’s a practical cadence for guiding the eye in a scrollytelling page?
randomly changing chart types
one idea per view with progressive annotation
all insights at once in a single dense graphic
auto‑playing transitions with no text
