Join Ray Villalobos for an in-depth discussion in this video Using external data, part of D3.js: Data Visualization.
…So far, we've been using data generated by a small loop at the top of our script.…Now, in reality, you'll probably want to use data that has been either…generated by some sort of database in a file or loaded up from a spreadsheet.…Now, ring div from external sources couldn't be simpler in D3.…As a matter of fact, it provides a lot of convenient functions for it.…But there are some issues that come with it, so let's take a look.…To set this up, I'm going to create a new file in that same folder as my project and…I'm going to call this data.tsv.…
And that stands for tap separated values.…So I'll hit Save.…All you would do in a TSV file would be to type in some columns, so say you wanted to…do something like month, and then value, or data, and then you would put in…maybe some months here, and then hit Tab, and then you would put a number.…And then you would do the same thing for another line and…just get a bunch of values.…Now, my data here is pretty simple.…I just need some data.…I don't need it to be tabbed, separated technically.…
