Exploring the World of D3.js with an Interactive Example

Struggling to grasp D3, I'm having difficulty executing the circle example.

http://mbostock.github.com/d3/tutorial/circle.html

I aim to run the part where the circles change colors and sizes.

I simply copied and pasted the example but can't figure out how else to proceed.

Trying to follow the tutorial to solve this problem :

http://jsfiddle.net/H2SKt/1/

In the pie chart, the labels are obstructing each other. What adjustments should I make so that all labels point towards the center of the chart? I've been adjusting the text anchor property without much success.

Any assistance is greatly appreciated :)

Answer №1

First and foremost, there is no need to copy the HTML code provided below to your website:

<svg width="360" height="180">
  <circle class="little" cx="180" cy="45" r="12"></circle>
  <circle class="little" cx="60" cy="90" r="12"></circle>
  ...
</svg>

This code snippet utilizes d3.js to create elements in the SVG. To make it work, you simply need to write JavaScript code that selects an SVG element (or appends one to your body) and generates the elements. The reason your code fails is because svg is not defined.

To learn more about creating elements with d3.js, refer to the Creating Elements section in the circle tutorial.

For a functional example, check out this working jsFiddle.
