Abstract—Networks have remained a challenge for information visualization designers because of the complex issues of node and link layout coupled with the rich set of tasks that users present. This paper offers a strategy based on two principles: (1) layouts are based on user-defined semantic substrates, which are non-overlapping regions in which node placement is based on node attributes, (2) users interactively adjust sliders to control link visibility to limit clutter and thus ensure comprehensibility of source and destination. Scalability is further facilitated by user control of which nodes are visible. We illustrate our semantic substrates approach as implemented in NVSS 1.0 with legal precedent data for up to 1122 court cases in three regions with 7645 legal citations. Index Terms — Network visualization, semantic substrate, information visualization, graphical user interfaces. 1

Our perceptive of the scientific datasets has largely relied on numerical and statistical analysis of data from experimental dimension and computer simulation result. In particular, we consider a simulated 3D time-varying model of scientific datasets and examine the temporal and collaboration among datasets. Our goal is to contrive effective visual representations to assist scientists in ascertaining temporal and collaborative among intricate and apparently chaotic scientific datasets. We propose a hybrid application with combination of streamline for iconic representation, global and local colour scale for temporal correlation, opacity scheme for spatio-temporal collaborative depiction and grid computing technologies as infrastructure for remote scientific visualisation. We illustrated also few images that can offer an effective tool for visually mining 3D time-varying scientific datasets.

Networks have remained a challenge for information visualization designers because of the complex issues of node and link layout coupled with the rich set of tasks that users present. This paper offers a five-layer hierarchy of network visualization situations with associated tasks: from simple node and link situations to more elaborate situations involving node labels, directed links, node attributes, and link attributes. Then, it offers a strategy based on tying node placement to node attributes within nonoverlapping regions. These user-defined meaningful substrates enable users to easily see which links remain within a region or cross to other regions. Link visibility is controlled by check boxes so that selected subsets of links can be displayed. To further limit display clutter, users can set sliders to control which nodes within a region have their edges visible. We illustrate our meaningful substrate approach in a modest example with legal precedents for 49 cases with 368 precedents, and show these in our implementation of NVMS 1.0.

Abstract — Ion dynamics has largely focusing on statistical analysis of collected data from experimental or simulation results. But unfortunately, the details of the structure-transport relation-ships in the data have been flout in favour of ensemble average. In specifically, we deliberate a simulated 3D time-varying model of ion dynamic in glass structure and scrutinize the spatio-temporal relationship among ion dynamics. Our main aims to conceive effective representations to sustain physicist in pinpoint probability of collaborative behaviours with their spatio-temporal correlation among convoluted and seemingly messy molecule movements in ion dynamics. But it is not possible at moment. Here, we highlight the broad issues of representing ion dynamics in glassy with relation to timeline events. We put forward a hybrid scheme that used 3D glyphs for representing orientation of ion dynamic, colour scale with codeword for portray the timeline events and opacity for collaborative events. With an anthology of the schemes, we illustrated that this scheme would be able to propose an efficient tool for visually mining for whichever 3-dimensional time-varying datasets.
