A grid-based heatmap visualization that maps activity intensity across days of the week and hourly time slots. Each cell is color-coded from light to dark, representing relative frequency or magnitude, making it easy to spot peaks, low-activity hours, and daily patterns at a glance. A hover tooltip provides exact values with precise day and time context. The smooth gradient legend below indicates data density, helping users interpret values intuitively. Ideal for analyzing user activity, workloads, or scheduling insights.

Functionality

• Weekly grid layout: days (Mon–Sun) × hours (1pm–6pm).

• Color intensity scale for relative activity/frequency.

• Tooltip on hover: shows exact day, time, and value.

• Dynamic legend (Less → More) for easy density interpretation.

• Highlighting for selected cell to focus on details.

• Responsive design with smooth transitions.

• Works with real-time or historical datasets.

Use cases

• Track app usage by time of day and day of week.

• Identify peak business hours in customer support or sales.

• Optimize content publishing times for social media.

• Analyze employee productivity or shift activity.

• Spot trends in IoT sensor data or system monitoring logs.

• Academic schedules or student attendance visualization.
