Infographics & Diagrams: Nano Banana Prompts
Create educational graphics, process diagrams, and data visualizations with Nano Banana. Turn complex data into clear visuals.
Visualizing complex information is hard. Nano Banana simplifies this by generating structured diagrams, flowcharts, and infographics that are both visually appealing and textually accurate.
Understanding Data Visualization
The challenge with AI infographics is structure. AI likes to hallucinate random shapes. To get a usable diagram, you must be extremely specific about the Layout (circular, linear, pyramid) and the Labels (what text goes where).
PROCESS FLOW
Let's start with the foundation example from the Text & Design overview. Here is the complete, fully detailed prompt to generate the "PROCESS FLOW" diagram.
[Optional Base Image] Create a 4-step circular process diagram.
Layout:
- **Structure**: Circular cycle (clockwise flow)
- **Steps**: 4 distinct nodes connected by curved arrows
- **Center**: Empty space or central icon
Content:
- **Node 1 Label**: "Research" (Top)
- **Node 2 Label**: "Design" (Right)
- **Node 3 Label**: "Build" (Bottom)
- **Node 4 Label**: "Launch" (Left)
Style:
- **Art Style**: Clean flat vector art (corporate Memphis style)
- **Palette**: Professional blue and teal gradient
- **Background**: White or very light grey
- **Icons**: Simple minimal icon for each step
Why This Works
The "Clockwise Flow": Specifying the direction helps the AI organize the arrows correctly. Without this, you might get arrows pointing randomly.
The Positional Labels: Telling the AI exactly where each label goes ("Top," "Right," etc.) prevents text overlapping.
The "Flat Vector Art": This style is standard for infographics because it's clean and scalable. It avoids unnecessary texture that makes text hard to read.
Common Mistakes
Note:
Data Accuracy: Do not use Nano Banana to generate a chart from raw data (e.g., "Graph this CSV file"). It cannot do math. It draws pictures of charts. Use it for qualitative diagrams (concepts), not quantitative data (exact numbers).
Variations on "PROCESS FLOW"
Change the structure for different types of information.
The Timeline (Linear)
Show history or steps in order.
Create a horizontal timeline infographic.
- **Topic**: "Coffee Brewing Process"
- **Layout**: Left-to-right linear flow
- **Step 1**: Coffee beans icon labeled "Grind"
- **Step 2**: Pouring water icon labeled "Pour"
- **Step 3**: Coffee cup icon labeled "Enjoy"
- **Style**: Warm, rustic illustration style
- **Connectors**: Dotted line connecting steps
What Changed: We switched to a "linear flow" and "illustration style" to match the artisanal subject matter.
The Bar Chart (Comparison)
Visualize growth or comparison.
Design a simple bar chart visualization.
- **Title**: "2024 Revenue" at the top
- **Axes**: X-axis labeled "Q1, Q2, Q3, Q4"
- **Data**: 4 bars of increasing height (upward trend)
- **Colors**: Blue bars on white background
- **Style**: Modern corporate 3D render
What Changed: We described the visual shape of the data ("increasing height") rather than the numbers themselves.
Expanding Your Visuals
Create more complex educational graphics.
The Anatomy Diagram (Medical/Technical)
Label parts of an object.
Create a labeled anatomy diagram of a DSLR camera.
- **Subject**: Cutaway view of a camera lens
- **Labels**: Lines pointing to "Lens", "Sensor", "Mirror"
- **Style**: Technical blueprint or line drawing
- **Background**: Blueprint blue or clean white
- **Detail**: High precision technical illustration
The Mind Map (Brainstorming)
Visualize connected ideas.
Create a creative mind map diagram.
- **Central Node**: "Creativity" in a cloud shape
- **Branches**: 5 colorful branches radiating outward
- **Keywords**: "Art", "Music", "Writing", "Code", "Design"
- **Style**: Hand-drawn marker style on whiteboard
- **Vibe**: Brainstorming, energetic, messy
