Treemaps for space-constrained visualization of hierarchies

Treemaps for space-constrained visualization of hierarchies

Tree structured node-link diagrams grew too large to be useful, so I explored ways to show a tree in a space-constrained layout. My initial design simply nested the rectangles, but a more comprehensible design used a border to show the nesting. My excitement about treemaps was great and like many innovators I thought millions of users would be using this tool within a few years. Related:  Data Visualising

Concept map An Electricity Concept Map, an example of a concept map A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts.[1] It is a graphical tool that designers, engineers, technical writers, and others use to organize and structure knowledge. A concept map typically represents ideas and information as boxes or circles, which it connects with labeled arrows in a downward-branching hierarchical structure. Overview[edit] A concept map is a way of representing relationships between ideas, images, or words in the same way that a sentence diagram represents the grammar of a sentence, a road map represents the locations of highways and towns, and a circuit diagram represents the workings of an electrical appliance. Concept maps were developed to enhance meaningful learning in the sciences. Differences from other visualizations[edit] History[edit] Various attempts have been made to conceptualize the process of creating concept maps. Use[edit] See also[edit]

How It Works The Visual Thesaurus is an interactive dictionary and thesaurus which creates word maps that blossom with meanings and branch to related words.

Vintage data visualization: 35 examples from before the Digital Era This is a guest post by Tiago Veloso, the founder of Visual Loop, a collaborative digital environment for everything related to information design and data visualization. He lives in Brazil, and you can connect with him online on Twitter and LinkedIn. If you follow us regularly on Visual Loop, you’ve probably noticed we like to featured not only modern interactive visualizations and infographics, but also examples from the past, from the time when there were no computer softwares to help analyzing and designing and no Internet to access and share data. Graphics, charts, diagrams and visual data representations have been published on books, newspapers and magazines since they exist, not to mention old maps and scientific illustrations, and despite the lack of tools such as the ones we have at our disposal nowadays, they are as inspiring and important as the best contemporary visualizations.

Data Visualization: Top 20 Amazing Tools | DATA SCIENCE REPORT - TODAY! It’s often said that data is the new world currency, and the web is the exchange bureau through which it’s traded. As consumers, we’re positively swimming in data; it’s everywhere from food labels to World Health Organisation reports. As a result, for the designer it’s becoming increasingly difficult to present data in a way that stands out from the mass of competing data streams. MR5RZMKG9XBF One of the best ways to get your message across is to use a visualisation to quickly draw attention to the key messages, and by presenting data visually it’s also possible to uncover surprising patterns and observations that wouldn’t be apparent from looking at stats alone. As author, data journalist and information designer David McCandless said in his TED talk: “By visualising information, we turn it into a landscape that you can explore with your eyes, a sort of information map. There are many different ways of telling a story, but everything starts with an idea. 01. iCharts 02.

Statistiques européennes sur les accidents du travail Source : Eurostat Analyse des statistiques par sexe et tranche d'âge Les accidents du travail sont beaucoup plus fréquents chez les hommes que chez les femmes, avec un ratio d'incidence plus de deux fois plus élevé (et trois fois en Allemagne). La dangerosité des métiers plutôt exercés par les hommes expliquent en partie cette différence importante, mais l'attention plus grande portée à la prévention des risques par les femmes n'est certainement pas étrangère à cette grande disparité. La fréquence et la gravité des accidents augmente sensiblement et régulièrement avec l'âge (baisse de la faculté de récupération de l'organisme), mais on assiste aussi à un déplacement des secteurs les plus à risque vers ceux où l'on retrouve beaucoup de jeunes travailleurs qui sont moins formés, moins expérimentés, avec notamment des emplois précaires (saisonniers, intérimaires…).
