Radial Bar Chart

Chart overview

Radial bar charts display categorical data in a circular format, with bars extending outward from the center.

Key points

  • They create visually engaging displays for cyclical data like time-of-year patterns or progress metrics, though they can be harder to read precisely than standard bar charts.

"Create a radial bar chart showing 'Average Monthly Temperature' for Seattle across all 12 months. Generate realistic Pacific Northwest data in Fahrenheit: Jan (42), Feb (44), Mar (48), Apr (52), May (58), Jun (64), Jul (68), Aug (69), Sep (63), Oct (54), Nov (46), Dec (42). Arrange months clockwise starting from January at top. Color bars using a temperature gradient (blue for cold ≤50°F, yellow for mild 50-60°F, orange/red for warm ≥60°F). Add temperature labels at the end of each bar. Include concentric circular gridlines at 30°, 45°, 60°, 75°F. Add a center annotation showing annual average (54°F). Title: 'Seattle Monthly Temperature Profile'."

# Create figure

# Calculate angles

# Set month labels

# Grid lines

# Title
plt.title('Seattle Monthly Temperature Profile', pad=20, fontsize=14)

# Colorbar

# Adjust layout

# Remove the radial axis labels for cleaner look
