D3 is a “newish” visualization library that has been getting a lot of attention recently. The New York Times has been using it extensively to create visualizations, and in fact its creator is currently employed by the NYT. I’d been meaning to take D3 for a spin for a while but couldn’t find a dataset I wanted to play with until a few weeks ago.
At the end of November, the LA Times published a dataset titled Capital appreciation bonds which highlighted how various California school districts were funding various projects with extremely high interest rate bonds. The LA Times described the data as:
Hundreds of California school and community college districts have financed construction projects with capital appreciation bonds that push repayment far into the future and ultimately cost many times what the district borrowed. Government finance experts consider bonds imprudent if the total cost is more than four times the money borrowed or the maturity period is greater than 25 years.
Anyway, you can check out my attempt at a visualization here.
