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.

Menu

One attribute

Comparing two attributes

One attribute with sorting

Three attributes

Viz

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

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