I'd like to create a simple pie chart in d3.js. The request response that I'm working with looks like this:
{"record":[{"status":"request"},{"status":"requirements"},{"status":"request"}]};
From what I've seen in examples, I need to convert that object to this:
[{"label":"Request", "value":2}, {"label":"Requirements", "value":1}];
I'm happy to use d3 functions or underscore or straight javascript to accomplish this, I just haven't been able to crack it on my own. Any help would be much appreciated!
You can use d3.nest()
to reformat your data:
var data = d3.nest()
.key(function(d){ return d.status; })
.rollup(function(leaves){ return leaves.length; })
.entries(input.record)
.map(function(d){ return {label: d.key, value: d.values}; });
