A few organizations track significant epidemics (and any pandemic), and fortunately, they publish their work as open data. This is because species is a categorical variable with these different values : ['setosa', 'versicolor', 'virginica'] , so color_continuous_scale is simply ignored. color_continuous_scale (list of str) – Strings should define valid CSS-colors This list is used to build a continuous color scale when the column denoted by color contains numeric data. Above are 3 examples using different methods: scale_fill_gradient() to provide extreme colors of the palette scale_fill_distiller) to provide a ColorBrewer palette scale_fill_viridis() to use Viridis. A guide to creating modern data visualizations with R.
