[Issue Resolved]

I am getting a dialog box that pops up in my Firefox Browser:

Title: "Confirm"

Text: "This web page is being redirected to a new location. Would you like to resend the form data you have typed to a new location?"

Buttons: "OK", "Cancel"

It is for the new D3.js course:

http://teamtreehouse.com/library/d3js

It only happens when I try to play the videos from the section of the course labelled:

Styling and Scaling with Data

(notice the funny "obj" symbolds appended onto the end of the section --this is a direct copy/paste from the course web page)

So it effects the following:

1.Using Linear Scales in D3.js

2.Using Time Scales in D3.js

3.Adding Axes to Your Visualization

4.Using the SVG Group Element

Whether I press "OK" or "Cancel", the videos play to the end,

but then I don't seem to get credit (points) for viewing the videos.

When I try to go back into these videos it doesn't give me an option to "replay" or "resume",

..it just acts like I've never viewed them before.

I'm using Firefox version 28 --the last version that was compatible with my plugins --including patrickjdempsey's old discontinued Luddite UI add on, version 0.2.11:

I have tried restarting my browser and my computer and it still does the same thing.

Don't know what's going on..any thoughts?

I guess I will try it in SRWare's Iron - a chromium variant (which allows plugins like Ad Block Plus) which:

aims to eliminate usage tracking and other privacy-compromising functionality that the Google Chrome browser includes..

..per it's Wikipedia page:

http://en.wikipedia.org/wiki/SRWare_Iron

I'll let you know how it goes..thanks for the "debugging opportunity"..

Edit1 (later):

Okay, tried it in SRWare Iron and Chrome (Version 40.0.2214.115 m)

Still not getting credit/points for the videos after they have played through.

Somewhat annoying

Oh well...I guess while I'm waiting for mods to notice this thread,

I'll append on a brief review of the course..

You are know I was really looking forward to this course from this forum post:

https://teamtreehouse.com/forum/forcedirected-graph-layout-implementation-using-position-verlet-integration

But there was no force layout examples:

..not using the three.js for 3D forced layout:

..not even using quadtree clustering:

http://bl.ocks.org/4ndr01d3/2686646672a92aa89a0e

..not even a single forced directed layout using Voronoi diagramming:

http://christophermanning.org/projects/voronoi-diagram-with-force-directed-nodes-and-delaunay-links/

..or spherical Voronoi example:

http://www.jasondavies.com/maps/voronoi/

What about d3.js for bubble cursors:

I guess I'll just keep exploring the various github sites and blogs/tutorials for D3.js to "fill-in-the-blanks" for what this course omitted..

Maybe down the road there will be an "advanced" data visualization course that will do a "deep dive" exploration of using D3.js and three.js together.

I actually have in mind a personal genomics example I want to build

which does a lot of bioinformatics data referencing...for use in clinical settings

as personal DNA markers need to be explained to patients

who pay for personal genome sequencing.

Hopefully I'll be able to simulate in a browser

some of the graphics of this java app:

I've just started playing around with the free downloadable version 3.3 of BioLayout Express:

http://www.biolayout.org/download/

..which has:

export of graphs to D3.js/HTML for display in a web browser..

If anyone else is doing anything DNA-related with D3.js or three.js please feel free to post some links.
