In python. Write a function, called the$\_48,$ which takes no arguments. Using free and open source tools, provide a set of choropleth visualizations for each of the columns containing dates such that the resulting visualizations $(48$ states only$)$ tell the story by conveying through color, texture, or both the time lines of achievement of each milestone$/$column in the provided dataset. Missing data are of particular

interest in that when a state has never achieved a given milestone, that should be

indicated in a standout manner such as cross$-$hatching. Consider that the publication may be grayscale. Provide a solution for that as well. Provide the

titles, labels, and legends necessary for clarification. File support is given as

follows: SturmCodebook has the explanation. SturmData is the data CSV$.$
