This video explains where to find more on remaining D3 data handlers HTML and XHR plus SQL.
- [Instructor] So far, we've looked…at five groups of data loaders.…CSV, JSON, XML, TXT, and HTML.…They each supply the data…to the webpage in quite different ways.…But we get hold of them in quite similar ways.…In fact, all of these so-called convenience methods…are part of something called d3 request…which has the following structure,…in d3 speak we have d3.request(url)…which means load the file at location url.…Then for some of the handlers we have .row…which lets us format the data as we load it.…
For all of the handlers we have .get…which is where we do something with the data…such as display it as a chart.…In d3 terms, the do something part…is called the callback function.…We can play with this structure quite a bit.…For instance, we could write…exactly the same function like this.…Formatting by row is still possible…for tabular formats like CSV.…D3 works out which function is for which purpose…by its location within the brackets.…Now you could write the functions out long form.…
