This is a flat glyph histogram of astrophotography images found in the Yahoo Flickr Creative Commons 100M Dataset. The histogram axis is year, and in each column, camera models, represented by glyphs, are sorted by camera maker, camera type, and how popular the model is in our dataset. The plot is made by coercing ggplot to make a histogram using geom_point() shapes.
