clustergrammer/src/sidebar/disable_sidebar.js

This is a clustergram implemented in D3.js. I started from the example http://bost.ocks.org/mike/miserables/ and added the following features

module.exports = function disable_sidebar(params){

  d3.selectAll(params.root+' .btn').attr('disabled',true);
  d3.select( params.viz.viz_svg ).style('opacity',0.70);

};
