Discovr
Discovr is a series of apps for the Apple iOS platform by David McKinney, which is characterized by using nodes to represent relationships between media in a tactile and visual way. There are apps for browsing music and movies. In October 2011, Discovr announced that the apps had passed one million downloads and $1.1 million in revenue. Operation The user interface is based on radial layouts where a node is connected to 1-6 other nodes. It displays an interactive, graphic map. The user begins by searching or browsing a pre-selected set of recommended items. Tapping causes a node to expand, to display related items. Double-tapping takes the user to a page of content about the artist or app. The interface uses a force-based layout algorithm which causes the new child nodes to pop out of the parent node, repelling nearby nodes, and quickly settle into positions that minimize overlap. The graph algorithm was developed by Tamás Nepusz, a PhD in graph theory who previously worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Inc
Apple Inc. is an American multinational technology company headquartered in Cupertino, California, United States. Apple is the largest technology company by revenue (totaling in 2021) and, as of June 2022, is the world's biggest company by market capitalization, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet, Amazon, Meta, and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user interface ...

Radial Tree
A radial tree, or radial map, is a method of displaying a tree structure (e.g., a tree data structure) in a way that expands outwards, radially. It is one of many ways to visually display a tree, with examples extending back to the early 20th century. In use, it is a type of information graphic. Basic layout The overall distance "d" is the distance between levels of the graph. It is chosen so that the overall layout will fit within a screen. Layouts are generated by working outward from the center, root. The first level is a special case because all the nodes have the same parent. The nodes for level 1 can be distributed evenly, or weighted depending on the number of children they have. For subsequent levels, the children are positioned within sectors of the remaining space, so that child nodes of one parent do not overlap with others. There are many extensions to this algorithm to create more visually balanced layouts, to allow a user to navigate from node to node (changi ...

Force-based Algorithms (graph Drawing)
Force-directed graph drawing algorithms are a class of algorithms for drawing graphs in an aesthetically-pleasing way. Their purpose is to position the nodes of a graph in two-dimensional or three-dimensional space so that all the edges are of more or less equal length and there are as few crossing edges as possible, by assigning forces among the set of edges and the set of nodes, based on their relative positions, and then using these forces either to simulate the motion of the edges and nodes or to minimize their energy. While graph drawing can be a difficult problem, force-directed algorithms, being physical simulations, usually require no special knowledge about graph theory such as planarity. Forces Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing. Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneous ...

Graph Drawing
Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics. A drawing of a graph or network diagram is a pictorial representation of the vertices and edges of a graph. This drawing should not be confused with the graph itself: very different layouts can correspond to the same graph., p. 6. In the abstract, all that matters is which pairs of vertices are connected by edges. In the concrete, however, the arrangement of these vertices and edges within a drawing affects its understandability, usability, fabrication cost, and aesthetics. The problem gets worse if the graph changes over time by adding and deleting edges (dynamic graph drawing) and the goal is to preserve the user's mental map. Graphical conventions Graphs are frequently drawn as node–link ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Last Fm
Last.fm is a music website founded in the United Kingdom in 2002. Using a music recommender system called "Audioscrobbler", Last.fm builds a detailed profile of each user's musical taste by recording details of the tracks the user listens to, either from Internet radio stations, or the user's computer or many portable music devices. This information is transferred ("scrobbled") to Last.fm's database either via the music player (including, among others, Spotify, Deezer, Tidal, MusicBee, SoundCloud, and Anghami) or via a plug-in installed into the user's music player. The data is then displayed on the user's profile page and compiled to create reference pages for individual artists. On 30 May 2007, it was acquired by CBS Corporation via its streaming division CBS Interactive, today a part of Paramount Global, for £140 million (US$280 million). The site formerly offered a radio streaming service, which was discontinued on 28 April 2014. The ability to access the large catalog ...
