I used logarithmic scale and normalized per million people, so despite the ugliness the exponential growth is quite clear, even in countries with relatively few cases.

I've been plotting this data myself for a few countries in EU over the past days, and the trend is plainly visible.
Steps to reproduce the effect:
1) Load https://github.com/CSSEGISandData/COVID-19/blob/master/csse_... into your favourite data processing package (mine is Excel, here's the PowerQuery for data mangling I did, valid up to yesterday's cases: https://gist.github.com/TeMPOraL/2a26d3a1da551fb818efce87493...),
2) Select Italy and other countries of interest, and plot on a log scale.
