- Is the data organized by the component most important to the narrative?
- geographic -> map
- temporal -> timeline
- ordinal -> table
- Do we have sufficient narrative context to understand the meaning of the data?
- If the data is vulnerable to being misinterpreted, have we adequately warned against it?
- Does the data mean we what think it means? (Are we very, very sure?)
- Is the data internally complete? (e.g., no missing years) If not, do we make it clear what data is missing?
- For example, in a chart: dotted or missing lines and a corresponding footnote
- In a table: “n/a” in the table cell, or an asterisk + footnote
- Have we been careful to ensure we don't treat "0" and "null" interchangably?
- Does any bucketing of the data effectively represent the distribution? (quartiles, quintiles, equal-interval, jenks breaks, box plot, etc.)
- Is the headline human-friendly? (conversational, non-technical)
- Are quotes in the headline singular and escaped? (‘)
- Does the Source line link back, if possible?
- Does the Credit line include everyone who worked on the graphic?
- Do the footnotes explain all caveats a normal reader would need to know to understand the chart fully?
- Does the graphic respond correctly? Does it read well on mobile? (e.g., nothing is cut off, text is readable, hover states disabled)
- Are we only including data we’re actually displaying (to keep page weight down)?
- Have you created a static fallback image for your final graphic? (fallback.png)
- If there have been late edits to your graphic, have you updated the fallback image?
- Are all links out target="_blank" so they don't open inside the iframe?
- Does the chart have a zero-baseline? (Or a very compelling reason for not having a zero-baseline?)
- Is there a grid line at the maximum value of the chart?
- Do the grid lines break at reasonable intervals?
- Are axes, labels, margins and colors consistent between charts that display related information? (small multiples, etc.)
- Are colors readable by someone who is red/green colorblind?
- Are the number of axis labels reasonable at various screen sizes?
- Does the entire chart fit within a normal user’s viewport?
- Is the the sort order sensible?
- Is there a useful secondary sort order?
- Have any repetitive unit labels been moved to the header? (%, $)
- Are all numeric values within a column rounded to the same number of decimal places?
- Has the graphic been edited?
- Has the graphic gone through a copy edit?
