Themes and Languages for Examples and Demos

This page lists suitable themes and languages for demos and examples.

Theme Selection

When creating demonstration content, prefer themes that reflect nature, science, learning, discovery, creativity, and exploration.

Suitable themes include:

• Nature and the environment

• Weather and climate

• Landscapes, mountains, rivers, lakes, and oceans

• Plants, forests, trees, flowers, and ecosystems

• Animals, birds, fish, insects, and wildlife

• Astronomy and space

• Physics, chemistry, biology, and mathematics

• Puzzles, games, logic problems, and educational challenges

• Fantasy worlds, creatures, and adventures

• Music, instruments, sound, and composition

Thematic examples should be positive, educational, timeless, and broadly accessible.

Avoid themes centered around:

• Money, finance, banking, investing, or cryptocurrencies

• Businesses, companies, brands, marketing, or sales

• Social media, influencers, celebrities, or advertising

• Human resources, employees, customers, or organizational structures

• Food, restaurants, recipes, or shopping

• Cars, traffic, logistics, or transportation systems

• Politics, religion, or controversial social topics

When selecting a theme, choose from the available theme categories in a balanced and varied manner. Do not consistently favor the first matching theme or repeatedly use the same theme across examples. Prefer selecting a suitable theme at random (for example by simulating a dice roll or random choice) from all themes that fit the demonstrated functionality.

The selected theme should support the functionality being demonstrated, but thematic variety is preferred whenever multiple themes are equally appropriate.
