User:MPopov (WMF)/Wikimania 2021 Hackathon

This page is for Graph-powered data visualizations of Wikidata Query Service (WDQS) usage (from 2015 to April 2021) as a replacement for soon-to-be decommissioned Discovery Dashboards – specifically the WDQS dashboard (see T227782 for more details). This project was completed by Mikhail Popov (aka bearloga) for Wikimania 2021 Hackathon.

Data
The original TSV was processed using R and uploaded as tabular datasets to Data namespace on Wikimedia Commons:
 * Data:Sandbox/MPopov_(WMF)/WDQS_homepage_traffic.tab
 * Data:Sandbox/MPopov_(WMF)/WDQS_SPARQL_endpoint.tab
 * Data:Sandbox/MPopov_(WMF)/WDQS_LDF_endpoint.tab

The code used to process and re-format the data can be found here.

Homepage traffic
Non-automata visits made to query.wikidata.org
