Hello, Welcome.

This API provides you to build a pie chart more easily. All you need is your data which has one column for category and one column for corresponding numerical values. This software will create a pie chart with colored categories and their sizes will follow the values in numerical column.

When using, just follow the following format where d[0] equals categories and d[1] equals numerical values. Also please name your data as "data.csv"

      
	var chart = pieChart()
      .x(function(d) { return +d[0]; })
      .y(function(d) { return +d[1]; });

	d3.csv("data.csv", function(data) {
	    d3.select("#vis")
	        .datum(data)
	        .call(chart);
	});

By doing this you will be able to create a simple pie chart. If you would like to change some features, you can use the following methods:

• Changing x values(categorical): chart.x(categories)
• Changing y values(numerical): chart.y(numbers)
• Changing the width: chart.width(w)
• Changing the height: chart.height(h)
• Changing the margins: chart.margin(m)
• Changing colors: chart.colors(c)

To give you an example of those methods, please see below.

      
	var chart = pieChart().height(650); // changes height to 650.
	

Width and height accept a single integer, x and y accept sets of categories or numbers, margin accepts an object with margins, and colors accept a list of colors.

If you have any other questions, please let me know. Thank you.
