Right now the visualization we're using isn't very interactive.  We just finished a better one and we'll deploy it soon, and you'll be able to hover to see specific daily values, zoom in, etc.  This should be deployed within the next week, but for now the best I can offer is the raw file with the data behind the graph.  You can find that here: https://metrics.wmflabs.org/static/public/datafiles/DailyPageviews/ruwikimedia.csv
