Pokemon

Create interactive visualizations for the Pokemon data. Complete the script so that when a user clicks on each menu button, there will be a different bar chart shown in the Viz block.

You will be reusing the code you wrote for generating SVG bar charts a couple weeks ago. The main challenge is to figure out how to connect your visualization code with the front-end code (event handlers ... etc).
