[waffle-basic] Basic Waffle Chart

[MarkusNeusinger]

Description

A waffle chart displays proportions using a grid of squares where colored squares represent parts of a whole. It provides an intuitive alternative to pie charts, making it easier to compare proportions accurately.

Key Features

• Grid of equal-sized squares (typically 10x10 = 100)
• Colored squares show category proportions
• Each square represents a fixed percentage (e.g., 1%)
• Easy to count and compare values

Applications

• Survey results and polling data
• Budget allocation visualization
• Progress towards goals (e.g., 73% complete)
• Demographic breakdowns

Data Requirements

• category (categorical) - Category labels
• value (numeric) - Proportions or percentages
• Values should sum to 100 or be normalized
• Size: 2-6 categories typical

Visual Elements

• Square grid (commonly 10x10)
• Distinct colors for each category
• Optional: icons instead of squares
• Legend identifying categories
• Optional: category percentages in legend

waffle-basic: Basic Waffle Chart

Description

A waffle chart displays proportions using a grid of equal-sized squares where colored squares represent parts of a whole. Each square typically represents 1% of the total, making it easy to count and compare values visually. It provides an intuitive alternative to pie charts, offering more accurate perception of proportions.

Applications

• Visualizing survey results and polling data to show response distributions
• Displaying budget allocation across spending categories
• Tracking progress towards goals (e.g., fundraising at 73% of target)
• Showing demographic breakdowns in population studies

Data

• category (categorical) - Category labels for each segment
• value (numeric) - Proportions or percentages for each category
• Size: 2-6 categories typical
• Note: Values should sum to 100 or be normalized to percentages

Notes

• Standard grid is 10x10 (100 squares) where each square = 1%
• Use distinct, contrasting colors for each category
• Include a legend identifying categories with their percentages
• Round values to whole squares for clean visualization
