It is similar to a pie chart, except sectors are equal angles and instead differ in how far each sector extends from the center of the circle. Named after the Finnish design company, Marimekko charts can be hard to read.Ī Nightingale Rose diagram is a type of histograph displayed in a circle. This type of visualisation is usually used to describe changes in quantitative data over time, and the relationships between different sets of data.Ī Marimekko graph is a type of bar graph where each bar is of equal length, and is divided into segments. Being densely packed with information, they tend to represent trading patterns over short periods of time, with each candlestick showing data for a single day.Ī line graph is a visualisation that displays data in a series of data intervals connected by straight lines. This style of visualisation is used to describe financial information such as price movements of a security, derivative, or currency. Visualisations that encourage the viewer to 'play' communicate the story behind the data with ease.Ī candlestick chart is a combination of a line-chart and a bar-chart: each bar represents all four important pieces of information. Interaction: Interactive visualisations add depth to data, and can be used to show variations. Do not expect your audience to engage in visual mathematics in order to understand your data. Simplicity: Simple visualisations are easy to interpret. This movement can be directed along the lines, edges, shapes, and colours within the visualisation. Movement: Designing a path for the eye to follow creates movement in a visualisation. While balance is traditionally achieved through symmetry, it can also be created using asymmetrical, radial, or scaled elements. Elements can emphasised by varying size, colour, texture, shape, etc.īalance & Scale: Distributing the visual weight of elements using colours, space, and texture creates hamony and balance. Contrast is traditionally achieved through colour, but size, shape, and textual contrast are also useful.Įmphasis: Differentiating part of the visualisation to catch the viewer’s attention. Beware of colour-combinations that can't be interpreted by people who are colourblind, such as red with green, and blue with yellow.Ĭontrast: Elements within a design can contrast with one another to reveal relationships and patterns. Repetition: Using pattern and repeated elements within a visualisation creates a sense of unity and helps to make the data appear more rhythmic and easy to understand.Ĭolour: Visualisations don't strictly need colour, but introducing colour helps to anchieve are more captivating design. Visual analytics is the practice of using visualisations to analyse data. In some research, visualisations can support more formal statistical tests by allowing researchers to interact with the data points directly without aggregating or summarising them. Even simple scatter plots, when the variables are chosen carefully, can show outliers, dense regions, bimodalities, etc. Information visualisation is another broad term, covering most statistical charts and graphs but also other visual/spatial metaphors that can be used to represent data sets that don't have inherent spatial components. Scientific visualisation is generally the visualisation of scientific data that have close ties to real-world objects with spatial properties. The goal is often to generate an image of something for which we have spatial information and combine that with data that is perhaps less directly accessible, like temperate or pressure data. The different scientific fields often have very specific conventions for doing their own types of visualisations. Data visualisation is an umbrella term, usually covering both information and scientific visualisation. This is a general way of talking about anything that converts data sources into a visual representation (like charts, graphs, maps, sometimes even just tables).
