• Cores sorted by frequency (highest to lowest)
• Dark theme with gray text and blue bars
• Auto-scales Y-axis to CPU's maximum frequency
• Refreshes every second

The visualization shows a horizontal bar chart where:

• X-axis: CPU cores (sorted by current frequency)
• Y-axis: Frequency in MHz (0 to max supported frequency)
• Blue bars represent current frequency of each core
