sine wave Generator
This visualization demonstrates the summation of three independently generated sine waves, combining them into a single composite signal. The line chart plots signal amplitude against sequential data points, with the combined waveform rendered as a continuous black line over a gray background. Built with D3.js, the example uses `scaleLinear` for both axes, a D3 `line` generator for the path, and custom `sineGenerator` functions that compute waveforms using the formula sin(2π·frequency·t). The code also leverages `observeResize` from `@drbagwell/responsive-viz-axes` for responsive sizing and displays axis labels for data points and amplitude.
