Click on the camera model in legend to toggle that camera's visibility or use the Next and Previous camera buttons.
Note that _12 indicates 12-bit data and _14 indicates 14-bit data.
Zooming is enabled.

Notes:
Optical black read noise except: 1 J1, 1 V1, D1 series, D2X, D3X, D3200(!), and most non-Nikon cameras.
The D3200 is an estimate, ISO 12800 is omitted.
These raw values are not appropriate for comparing camera models because they are not adjusted for gain or area.
The shape of the curve can tell you something about the amplifier circuitry of the camera.
Jagged curves, like the D3S show evidence of a separate amplifier for intermediate ISO.
Straight curves, like the D7000, show evidence of being dominated by photosite read noise.
Curved curves, like the D90, show evidence of being dominated by ADC read noise.
Quite a few cameras stop analog gain before reaching the "Hi" ISO values.
