Okay, let's create a classic monitor displaying an ECG waveform using HTML, CSS, and JavaScript with the Canvas API.

This setup creates the visual structure of a monitor and uses JavaScript Canvas to draw and animate a continuous, scrolling ECG waveform.

Okay, let's create a simulation of an airplane radar screen using HTML, CSS, and JavaScript Canvas.

This creates a circular radar display with concentric grid lines, a rotating sweep line with a fading trail, and several dots representing airplanes. The airplanes have a slight random movement added for visual interest.

Okay, let's enhance the radar simulation with more details like phosphor persistence for the blips, trails showing recent movement, and range markers.

This version adds:

• Phosphor Persistence: Blips fade gradually after the sweep passes.
• Movement Trails: Each blip leaves a short trail of its recent path.
• Range Rings & Labels: Concentric circles with distance markers (in simulated Nautical Miles).
• Azimuth Lines: Radial lines indicating direction.
• Blip IDs: Simple flight numbers appear next to bright blips.
• Dynamic Blips: Airplanes move, turn slightly, appear randomly, and disappear if they fly off-screen.
• Overlay Text: Static text elements for Range, Mode, and Status, typical of radar displays.
• Improved Visuals: More detailed sweep gradient and bezel styling.

The simulation now feels more dynamic and closer to a stylized representation of a real radar screen.

Okay, let's update the radar to display up to 100 airplanes. This will make the screen much busier.

We'll modify the JavaScript to:

1. Create 100 airplanes initially.
2. Allow the simulation to maintain up to 100 airplanes.

The key changes in script.js are:

• maxAirplanes constant set to 100.
• Initial loop for creating airplanes now runs up to maxAirplanes.
• The condition for adding new airplanes in the animate function now checks against maxAirplanes.
• Slightly adjusted trail length, airplane speed, and ID display frequency to better handle the increased number of blips.

The radar screen should now be significantly more populated. Performance might be a consideration with this many objects being drawn and updated, especially on less powerful devices, but canvas is generally quite efficient.
