7 Visual polish and data punch
Module 7 – Visual Polish & Data Punch
Why this module matters
Great content can still fall flat if the slides look cluttered or data is missing. In this lesson you’ll learn a fast routine to refine layouts, add high-impact visuals or charts, tighten copy, and ensure brand consistency—all inside Gamma in just a few minutes.
Learning outcomes
By the end of this module you will be able to…
• Adjust slide layouts for clarity and emphasis.
• Choose or swap images and icons that strengthen your message.
• Create quick charts in Gamma using small data tables from ChatGPT.
• Tighten on-slide text so visuals take centre stage.
• Run a Three-C sweep (Clutter, Consistency, Colour) to finish like a pro designer.
1 Do a layout pass
Click through each slide and ask:
• Does this idea need more space? Switch to a two-column or big-number layout.
• Is a bullet redundant? Move it to Speaker Notes or delete.
• Could an icon list replace wordy text? Use Gamma’s built-in icon blocks.
2 Select images and icons
• For concepts (heritage, sustainability, innovation) pick one Unsplash photo or AI image.
• For processes or lists add a simple icon beside each bullet. One visual per idea is enough.
3 Add quick charts with ChatGPT tables
When a number will convince your audience, ask ChatGPT for a mini table such as:
Year | Visitors (k)
2021 | 820
2022 | 950
2023 | 1 050
Copy the table into Gamma’s chart block and choose bar or line. Need comparisons? Request a table of “Jurisdiction | Average stay (days)” for your five benchmarks and drop it into a horizontal bar chart.
4 Tighten bullet text
Prompt ChatGPT:
“Rewrite every slide bullet to 10 words or fewer, start with a verb or number.”
Replace the originals so visuals and white space can breathe.
5 Run the Three-C Final Sweep
• Clutter – delete duplicate visuals or stray bullets.
• Consistency – check font sizes, icon style, image aspect ratio.
• Colour – confirm all charts and shapes use your brand palette.
