Several things are on display here for public scrutiny and enlightenment: Geraldine went through interesting phase transitions around 200 days and then again around 470 days, which does not follow the textbooks at all, which again is pretty normal. With our second girl Amélie we obviously figured out a few things and she's growing like crazy. This begs the question if this would extrapolate to a third girl. We have better things to do these days than to measure and survey our girls and consequently the data points are increasingly sparse as time unfolds. Against common wisdom, it is indeed possible to create decent looking graphics with Microsoft Excel if you care to fiddle around with the options long enough. This chart sports a stylish retro look because it is an hommage to the guy who invented it all back at the turn of the 19th century: William Playfair. Who are the girls anyway? There is Geraldine and there is Amélie and they have home pages.
