SVG line chart of vote-escrow balance decaying linearly from nowSec to unlockTime. Educational primitive -- shows the user how their vote weight will fade as the lock matures.

Linear-decay model (Curve / Aerodrome standard):

veBalance(t) = amount * max(0, unlockTime - t) / maxLockSec

At t = nowSec the line starts at the current ve-balance; at t = unlockTime it hits zero and stays there. The chart samples sampleCount points across that span and connects them with a polyline.

The amount cancels out of the normalised curve -- every plotted height is remaining(t) / remaining(nowSec), a ratio of two second counts -- so the geometry is computed entirely in integer space and the uint256 amount is never converted to a Float. It is only tested for zero (a zero balance draws a flat line on the axis). Coordinates are emitted in hundredths of a pixel.
