无法实现示例d3.js文件

Question

I tried to modify from this sample . https://bl.ocks.org/mbostock/1346395

I build a index.html and data.tsv with those codes inside .

Then ,I change <script src="//d3js.org/d3.v3.min.js"></script> to <script src="https://d3js.org/d3.v3.min.js"></script>

As a result , no charts are shown on index.html

Whats wrong with it?

I put index.html and data.tsv in same directory

the code I have made changes

<script src="//d3js.org/d3.v3.min.js"></script>
<script>....

to

<script src="https://d3js.org/d3.v3.js"></script>
<script>..... 

Result:

Console :

Answer 1

I guess the problem is - you need a local server to test it with your local data. d3.tsv() - makes ajax call so it needs a server.
