Here is the explanation for the preceding code blocks:
- Year is the list of years for which GDP data is to be plotted.
- China_GDP is the list of GDP in trillion dollars ($) for the years specified in the Year list, and similarly for US_GDP and UK_GDP.
- rax = plt.axes([0.05, 0.5, 0.15, 0.25], facecolor='skyblue') defines the axes where RadioButtons will be plotted, with the facecolor set to skyblue.
- radio = RadioButtons(rax, ('USA', 'China', 'UK')) instantiates the RadioButtons object on the given axes and with the given labels.
- countrydict() is the dictionary containing the country as key with associated GDP and the plot attributes color and linestyle as values.
- def GDP(label): defines the callback function that gets activated ...
