Fictional scenario: a civic team needs to explore invented building-energy records without presenting sample values as public facts.

The fictional brief asks for comparisons that remain understandable when values are missing or the sample is small.

• Avoid implying precision the sample cannot support.
• Explain the meaning and source of every displayed field.

The sample exploration defines a data dictionary, separates observed values from assumptions, and tests a table-first and map-first layout.

• Use units and date ranges next to values.
• Offer an accessible table alongside charts.

The proposed dashboard pairs a neighborhood overview with a sortable data table. Fictional demo outcome: the sample interface makes comparison states explicit; no real dataset or public impact is claimed.

• Clear empty, missing-data, and comparison states.
• All records in the demo are invented.

Tooling names are included as fictional editorial metadata for dashboard testing.

• Figma · Tableau concept · design tokens
• Color is never the only way to read a data state
