Graphical representation refers to the use of charts and graphs to visually display, analyze, clarify, and interpret numerical data, functions, and other qualitative structures. Show FAQsWhat is Graphical Representation?Graphical representation refers to the use of intuitive charts to clearly visualize and simplify data sets. Data is ingested into graphical representation of data software and then represented by a variety of symbols, such as lines on a line chart, bars on a bar chart, or slices on a pie chart, from which users can gain greater insight than by numerical analysis alone.
Types of Graphical RepresentationData charts are available in a wide variety of maps, diagrams, and graphs that typically include textual titles and legends to denote the purpose, measurement units, and variables of the chart. Choosing the most appropriate chart depends on a variety of different factors -- the nature of the data, the purpose of the chart, and whether a graphical representation of qualitative data or a graphical representation of quantitative data is being depicted. There are dozens of different formats for graphical representation of data. Some of the most popular charts include:
Advantages and Disadvantages of Graphical Representation of DataTabular and graphical representation of data are a vital component in analyzing and understanding large quantities of numerical data and the relationship between data points. Data visualization is one of the most fundamental approaches to data analysis, providing an intuitive and universal means to visualize, abstract, and share complex data patterns. The primary advantages of graphical representation of data are:
Why Graphical Representation of Data is ImportantGraphic visual representation of information is a crucial component in understanding and identifying patterns and trends in the ever increasing flow of data. Graphical representation enables the quick analysis of large amounts of data at one time and can aid in making predictions and informed decisions. Data visualizations also make collaboration significantly more efficient by using familiar visual metaphors to illustrate relationships and highlight meaning, eliminating complex, long-winded explanations of an otherwise chaotic-looking array of figures.
Does HEAVY.AI Offer a Graphical Representation Solution?HEAVY.AI's visual analytics platform is an interactive data visualization client that works seamlessly with server-side technologies HEAVY.AIDB and Render to enable data science analysts to easily visualize and instantly interact with massive datasets. Analysts can interact with conventional charts and data tables, as well as big data graphical representations such as massive-scale scatterplots and geo charts. Data visualization contributes to a broad range of use cases, including performance analysis in business and guiding research in academia.
Why are images so powerful?Images are highly evocative, this means that they elicit a strong emotional response in the viewer.Images are processed cognitively more quickly than written text, so meaning can be conveyed quickly and effectively through imagery.Images are open to interpretation- they can appeal to many different viewers and they can be used in many contexts. However, they are open to social, cultural, contextual and individual variation in the meanings they convey. GAZERefers to where the figure in the image is looking. DEMAND- a term used when a figure in the image 'gazes' directly out of the page at the responder. This establishes a connection between subject and viewer. OFFER- a term used when a figure 'gazes' at another object in the image encouraging us to look at that object, the viewer is a detached onlooker. READING PATHWAYS A reading path is the path you take through a visual text. The path moves from the most salient to the least salient elements.In other words, it is the movement of the viewer's gaze around a visual text. This can be influenced by elements such as vectors, Salience, gaze etc.VECTOR- A vector is a line that leads your eye from one element to another. A vector may be a visible line or an invisible one. It can be created by such things as against, pointing fingers or extended arms. They may be objects or parts of objects (such as arms, legs, a pole, the side of a house) or invisible lines such as the direction of gaze from a represented person's eyes to another person or object. SALIENCE ( focal points)- The element/s in an image which stand out and attract the viewer's attention, it refers to the feature in a composition that most grabs your attention. An image can be made salient through
FRAMING- elements in a layout can be disconnected and marked off from each other or connected. If elements are cut off from one another they are strongly framed. Framing can be achieved by borders, this discontinuities of colour and shape, for my white space. Connectedness can be achieved by vectors and devices such as overlapping or superimposition of images. PERSPECTIVE FOREGROUND/ MIDDLE GROUND/ BACKGROUND - what is in the foreground is often considered more important than what appears in the background.POSITIONING OF ELEMENTS eg centre or off-centre COMPOSITIONAL AXIS the vertical axis - the left is known, the right is new or unknownthe horizontal axis- the upper section is ideal, the lower elements are real.IDEAL/ REAL - when the page is divided horizontally, top and bottom. The top of the page is often called the 'ideal'. In advertising the product is usually placed in the ideal. What has been placed at the bottom of an image can be said to represent the 'real' and usually contains information about the product. JUXTAPOSITION Placing visual elements side by side to create contrast or interaction. The placement of two or more ideas, characters, actions, settings, phrases or words side-by-side for a particular purpose, for example to highlight contrast or for rhetorical effect. SHOTS AND PERSPECTIVESViewing angles and distance are very similar to film shot. For example, 'low angles' make the subject look more powerful while the reverse is true when a 'high angle' is used. A high angle makes the viewer feel a sense of power and a lower angle makes the viewer feel powerless. A straight on eyelevel view creates no power difference. Like in film medium, illustrators use 'shots' for different purposes, for example close-ups, long shots etc. SOCIAL DISTANCE A close-up is intimate and creates a connection with the viewer whilst a long shot creates objectivity and distance. With a long shot or an objective image of you is not drawn into involvement with the image. Meaning comes from the symbolic connection made by the reader.MODALITY/ CREDIBILITY
SYMBOLS symbols can be used to represent ideas or concepts. LIGHTING
COLOURColour is an element strongly tied to our emotions. Depending on the context, it can have symbolic, associative or evocative meanings.HUE- red, green, blue etcVALUE- the brightness of colour- light/ darkINTENSITY- describes Te purity or strength of a colour: bright or dull'Hot' colours- excitement, happiness, anger'Cool' colours- harmony, peace, sadnessPlacement of certain colours near each other can prompt mood, or draw attention to certain features Media used can emphasise colour, eg luminous watercolours, gouache- more intense.
