Took me 3 days to get all this working however, the first day was spent writing it in C# on IIS to make sure I understand how D3 worked. Thought I would post it, just in case someone else decided to use D3 within WebFOCUS and pull its data straight from a Synonym instead of loading it via CSV.

This example shows you how to setup WebFOCUS to use D3 and how to execute against a Hold file without the use of creating CSV's and loading via JS.

Setting up WebFOCUS was pulled from a document I got through the chain of people, which looks as if it derived from Summit 2014 User Conference. There was a PowerPoint and a Word document sent to me, both seem to be the exact same wording.

Snip it from Summit document, but altered a little:
Downloading and Installing D3

This step, downloading and installing the D3 JavaScript library. Installing and running D3 from the WebFOCUS Client / Repository will be covered later in this document.

Instructions:

1.	In your web browser go to http://www.d3js.org.
2.	At bottom of the first browser screen full (you might need to scroll down a little) click the link d3.zip. It will download the zip archive https://github.com/mbostock/d3...wnload/v3.4.8/d3.zip
3.	d3.zip contains three files.
   a.	LICENSE
   b.	d3.js – Delete
      i.	This file contains special characters that WebFOCUS cannot process.  D3 forums have many people yelling about this as far back as 2012 and it still has special characters.
   c.	d3.min.js – Keep
      i.	This is a compact version of d3.js and will do everything the same, but without the special characters.
4.	Create a folder on your PC, say, d3_zipped, and unzip d3.zip to it.
5.	Using your computer’s operating system utilities, say, Microsoft Windows’ File Explorer or the Unix/Linux shell, create a WebFOCUS application folder for d3, e.g.., [b]<WebFOCUS Server>\<drive>$\ibi\apps\d3[/b]
6.	Take the files unzipped in step 4 above and copy them to the d3 app folder created in step 5 above.
7.	Then, using the WebFOCUS Reporting Server console, add the d3 app folder to the Application Path.


I’m setup now, now what?
Now you need to figure out what D3 report you’re going to use.
1.	You can go to this URL to find different styles:
   a.	https://github.com/mbostock/d3/wiki/Gallery
2.	For this demo we are going to use:
   a.	http://bl.ocks.org/NPashaP/9796212
3.	Right click on page and view source.
4.	Click on the link that looks like this:
   a.	[b]/NPashaP/raw/9796212/8ed537693ddcb720b79cae93d979385c3c3b08c3/[/b]
5.	This will take you to that report only page.
6.	Right click on this report and view source.
   a.	You can click and download the d3.v3.min.js file if you like, but it’s the same as the d3.min.js you have already downloaded earlier.   Just make sure you are using the same name as the one you have in the ibi\apps\d3 folder.
7.	Download the bipartite.js file and place it in the same folder as the D3.min.js under the ibi\apps\d3 folder on the WebFOCUS server.


I have the report, how do I use it.
1.	Go into WebFOCUS or DevStudio and create a folder under content called D3 for this demo.  You can call it anything, but to be consistent, we will call it D3.
2.	Make sure the user you’re using has access to the CAR Synonym. 
3.	Right click and create a new FEX, however you would like to do it then save it and name it anything you like.
4.	Copy and Paste this code into your FEX.

];

bP.draw(data, svg);

</script>

   </body>
</html>

-HTMLFORM END


At the Finish Line
Run it and you should get a pretty graph using the CAR Synonym.

Keep in mind, this is a very simple version of using D3, but it shows how you can load this from a hold file instead of creating CSVs, then loading the CSV via Javascript.

Have a happy FOCUS day and let me know if you like of see something I should change to make this demo better.

I followed your directions here and the fex is in fact running but nothing is rendering on the report. I am running 8.1.05. Are there any additional settings that have to be in/off to recognize js content?

Thanks!

I was able to download the files and build this chart successfully, however theres a chart that my customer wants (sunburst with labels) has JSON formatted data in it as shown below. I'm hoping we can use FORMAT JSON but any thoughts on formatting in such a way?

Thanks so much

I am not a D3 expert but I googled d3 suburst with labels and found many examples. I think as long as you register them to WebFOCUS the same way you have done with others it should just work.


Thank you for using Focal Point!

Note that IBI states they work with D3 charts, but the reality is the D3 charts they are talking about were modified specifically for WebFOCUS by IBI. They have a page, somewhere of a list of D3 charts they can use right out the gate. Now, this doesn't mean your every day D3 chart can't be used. What you can do, is gather your own data, generating the format the D3 charts wants, like I did in the above example, then feed it into the chart. You could also create a separate fex, that generates the required data as some D3 charts want external sources.

It just takes a little bit of an imagination and you can make anything in WebFOCUS work. We wrote a full application using WebFOCUS, not a chart on the site at all. We started using charts, but then as the business changed requirements, we didn't want to have to rewrite what we already did. I didn't use their HTML Builder. Every HTML page is an actual FEX, than I push HTML out and have an external FEX pull the data required for the page. Just think of how it can be architected in your favorite language and do somewhat the same thing in WebFOCUS, while using Portal as the entrance and Magnify as the search engine to find what the customer is looking for.

This may be too much to ask but, would you have few minutes to look at it on webex with me. I feel like I'm close to putting labels but, not quite there yet.

			.attr("x", function(d) {

			.attr("dx", "6") // margin
			.attr("dy", ".35em") // vertical-align
			.text(function(d) {
				return d.name;
			});



Appreciate your time and thoughts!

I will have to leave that to Gavin, I really have limited experience with D3 charting.

Thank you Chuck,
Gavin, please send me an example for sunburst chart with labels. I really like these examples and lot of the charts are similar but our WF HTML Extensions seem a little different, I tried editing sunburst.js but gave up at some point.

Without spending too much time on this (from my part), I have looked through the sunburst.js and I would concentrate your efforts in the area where the segments are built (about line 455) and use what you learn from that section to build your text elements.

However, rather than just modifying the original com.ibi.sunburst at your installation, why not create it as a new HTML extension?

You could use the original as a template.

If you are planning on attending Summit this year then check out the sessions by Dan Weingart - Summit Agenda Link

I've written 4 to date - only one published on GitHub as two were customer specific requirements.

If you have a good understanding of JavaScript and an interest in charting then I commend learning D3. I would also suggest gaining an understanding of SVG graphics and, if you can, HTML canvas.

I've been meaning to try a 'WebFOCUS - D3 Mashup' for a while now. Glad to have the encouragement.

    Notes:
  • The code is currently calling D3 via a Content Delivery Network. I would probably download D3.js and host it from an application folder, as Gavin suggests, before thinking about actually using D3.
  • WebFOCUS has always integrated well with other technologies. WF <-> D3 is yet another example.
  • I would probably recheck to make sure one of the WF JSCHARTs didn't meet user needs, before implementing a D3 chart.
  • I know HOLD FORMAT JSON is a new 81 feature, but I haven't yet had a chance to experiment with it. If anyone else has, I'd love to hear of your experience with it.
  • I believe with 82, WF more fully supports D3, but being on 81, I haven't had a chance to review.

I am in need of implementing a timeline chart and have found that this D3 chart would work great https://github.com/jiahuang/d3-timeline .

Gavin/David anyone have an example of this? I have currently implemented a Google chart (https://developers.google.com/chart/interactive/docs/gallery/timeline#configuration-options) but have found it contains a bug with the tooltip which has not been fixed in the 4 years it has been known. I am doubtful it will be fixed anytime soon and it is causing the chart to be useless since tooltips are a must. I would much prefer to use the D3 charts anyway since they are easier to customize once you learn them.

thanks,

Marita Locklear
