Jurgen Altziebler explores the fascinating tennis rivalry between Roger Federer and Novak Djokovic, utilizing Elasticsearch, Logstash, and Kibana to create dynamic dashboards that visualize their match data. As of September 2015, the two players were tied with 21 wins each, with Federer initially dominating until Djokovic's rise in 2011. Their rivalry intensified over the past four years, with Djokovic winning 12 out of their 19 encounters, including four out of five grand slam meetings. Altziebler emphasizes the importance of knowing your data and creating coherent stories in dashboards, suggesting strategies such as grouping modules logically and testing designs with others. Despite Federer being in his mid-thirties, he maintains an impressive win rate, having won 83% of his matches over the last four years, including 310 matches in total, and the dashboards also highlight his encounters with Rafael Nadal while using Kibana's dark theme for improved visual presentation.
