It's Sunday afternoon, so it must be time for some #Acoustics #DataVisualization and this time it's all about musical instrument strings... You might remember my 'Acoustic Ashby chart' where I plotted bulk modulus versus density for various fluids. I've redrawn it with plotly; in due course there'll be a web version where you can hover over points to get the substance name etc, but for now here's a static plot.
