Heatmaps are an incredibly useful tool and ingeneous way of visualising and displaying data and relationships between columns and rows, whatever they may be. Basically, “a heat map is is a graphical representation of data where the individual values contained in a matrix are represented as colors”.
I first came across “heatmaps” in my studies in Molecular Biology at the University of Cape Town where they are very common to show gene expression of microarray data under various conditions and help identify clusters and patterns. For example, see the image below with the typical red and green colour scale used.
Sitting at my desk on a Monday morning, my stiff, scratched legs are a reminder of a weekend well spent, full of adventure and exploration!
I don’t often stop to take photos on a trail race, but the unexpected, overwhelming sense of exhilaration I felt as running through the mountains in Mont Rochelle Nature Reserve, forced me to pause, dig my phone out of it’s zip lock bag and try to do the experience justice with my panoramic shots. Either way, that sense of pure, natural, unburdened freedom is still lingering with me into the week.
