Vislet is a tool integrated into Memgraph Lab that allows for the visualization of graph data with geographic components by synchronizing vis-network and Leaflet to display nodes and edges on a world map. Geographic nodes, identified by latitude and longitude properties, are automatically detected and visualized, while non-geographic nodes remain hidden unless the map background is disabled. The tool offers features like panning, zooming, and maintaining node positions, enhancing the visualization of datasets such as neighboring countries. Vislet transforms the coordinate systems of vis-network and Leaflet into a unified system, ensuring accurate representation on the map. Although Vislet is in its early stages and allows for high customization, further development is anticipated to enhance its functionality and robustness.

Memgraph Lab's latest version introduces a versatile scripting language that allows users to customize the visual display of graph query results, offering a range of styling options for nodes and edges. Users can define style rules to adjust properties like color, size, and labels, with the ability to apply these rules universally or to specific nodes and edges using filters. The scripting language also supports complex functions, enabling dynamic styles such as node size proportional to city population, using mathematical methods like Newton's method for square root calculations. Moreover, it enhances data exploration by allowing the creation of visual cues, such as highlighting cities based on economic indicators like food and drink prices, thereby facilitating better data understanding alongside aesthetic improvements. This functionality effectively transforms Memgraph Lab into a tool for both data visualization and analysis, encouraging users to leverage these capabilities for deeper insights into their data.
