I would like to reproduce the shown periodic table, with more correct areas.

I would appreciate any ideas to how this can be done. How do I in TikZ calculate the area of one box? Can I make the control points auto adjust to a given area, either by iteration, or direct calculation. I do not know the math behind control points!?
Code sample:
\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (0,0) rectangle (3,2);
\draw (0,1) .. controls (0.4,0.4) and (1.5,1.5) .. (3,1);
\draw (1,0) .. controls (0.4,0.4) and (1.5,1.5) .. (1,2);
\draw (2,0) .. controls (1.4,1.4) and (1.5,1.5) .. (2,2);
\end{tikzpicture}
\end{document}
Output:
pgfplots
librarypatchplots
withpatch type=biquadratic
orpatch type=bicubic
... they would require points ON the boundary curves which makes things a little bit simpler.
