text: user643: 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?
  
  user77: 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.
  
  user1653: 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.
  Disclaimer: I am the creator of HiPiler.
  
  user1389: I would also recommend two very recent Hi-C visualization frameworks (with some public data available in both): HiGlass and JuiceBox.
