Pokemon Form

In the previous page, the selection of which attributes to visualize were hard coded. Let's make our viz more interactive and flexible by providing forms for users to select which attributes to visualize dynamically.
One attribute

Attribute (e.g., Attack):
Comparing two attributes

Attribute 1: Attribute 2:
One attribute with sorting

Attribute:
Three attributes

Width 1: Width 2: Color:
Viz

Data is not loaded yet
// pokemonData is a global variable
pokemonData = 'not loaded yet'

$.get('/data/pokemon-small.json')

     pokemonData = data
