The text discusses visualizing time-based graphs with Neo4j using the KeyLines Time Bar. To achieve this, one needs to load time-stamped data into Neo4j, create a client-side web application, send Cypher queries to retrieve data from Neo4j, parse the response into KeyLines' JSON format, and load the result into KeyLines. The process also involves adding interactivity to the time bar by binding functionality to its 'change' event. This allows the application to query Neo4j for new data when the user extends the date range, enabling real-time visualization of dynamic graphs.
