Can I look at D3 examples?

Next week im starting to work on d3 projects. I watched some tutorials on d3 and did the fcc challenges, but when i see treemap or heatmap i have no idea how to do that without checking some examples on sites like bl.ocks. Is it ok to check similar examples and then to the projects or try to figure out everything on my own?

Yeah, just checking out other D3 apps, no problem. Go for it. Checking out other people doing the exact same FCC projects - that is a little more questionable, but could be a last resort. Actually cutting and pasting from those projects, obviously that is over the line.
