|H(f)| = 1 / sqrt(1 + (2π f R C)^2). The plot shows |H| in dB vs. frequency and marks the cutoff
frequency fc = 1/(2πRC). Users can set R (Ω), C (μF), frequency range, point count, and choose
linear/log scales.
- Plotting library: Plotly.js

x = (R + r)·cos(t) − (r + O)·cos(((R + r)/r)·t),
y = (R + r)·sin(t) − (r + O)·sin(((R + r)/r)·t).
One-button start, with seeded/validated inputs (R, r, O), optional randomize/clear, and smooth animation.
Assignment 6 – JSON Crypto Viewer
