Let's see if we can collect the data first, and then worry about how to do the technical stuff, like the visualisation. Although I imagine it to be a 3d bar chart laid over a map of the UK.??
So, on Twitter, use the hashtag #UKdeepsnow and somewhere in the tweet include your postcode or town, and the depth of the snow, preferably in centimetres. I'm more interested in a crowdsourced, sel-reported set of data for this, rather than 'what the news says' it is in your area. If you don't know this, because you don't have a ruler and/or access to the snow outside, an approximation will do. And we'll assume that if you're 'a bit out' then so will everyone else so we should get a rough idea of the depth of the snow where you are.??
Okay, that is all.??
