I have identified a genomic region (CpG island) that is enriched for a characteristic of interest in the vast majority of my samples.

After viewing it in the UCSC genome browser, I have confirmed that it does not overlap any annotated gene promoters, gene bodies, or retrotransposons, but am convinced that it is functionally interacting with something long range.

Is there a publicly available visualization tool where I can input my genomic region and get a list of topologically associated domains from 3C or other chromatin-chromatin interaction data?

    $\begingroup$ What assembly is your genomic region of interest in? $\endgroup$

I would also recommend two very recent Hi-C visualization frameworks (with some public data available in both): HiGlass and JuiceBox.

If you have more than a dozen or even hundreds of regions that you want to compare you could check a companion tool of HiGlass called HiPiler. HiPiler lets you arrange, cluster, and pile up to thousands of genomic regions. Take a look at this 5min video introduction to see if the tool could help you to answer your questions.

Depending on the genome you want, you may be able to use the chorogeneome navigator, which is from some of my colleagues. This uses a number of public HiC datasets and allows you to view interactions.
