Hi Raymond. Currently we don't have any WMF-hosted tools that will let you get this information easily. We have committed to deliver a Pageview API by the end of this quarter [1]. The first version will not have per-category totals, but it will have per-article totals. Until then, there are community-built tools such as:
Google Big Query has also ingested our hourly pageview dumps, I've cc-ed Felipe Hoffa so he can provide details on that.
The main problem with the solutions above is that they're based on an out-dated pageview definition that's been having more and more problems lately. The Pageview API we are shipping at the end of this quarter will be based on higher quality data that makes an effort to detect spiders and normalize page titles across different access methods (API requests from mobile apps, different accents, etc). Preliminary tests show that this data does not have the anomalies we've seen in the old data.
