What is Data Visualisation?

"Data Visualisation", in general, means the representation of data in a visual form such as a chart, diagram, map and infographic. The aims of data visualisation are to effectively communicate with the audience and facilitate further data analysis.

Data visualisation is indeed important for researchers. By using visual representations of information, researchers can present an enormous amount of data in clear, cohesive and quick ways. Readers can thus draw conclusions, and easily discover general patterns, outliers and exceptions from the information. 

4 Major Phases of Data Visualisation Cycle

  • Data Extraction

    Researchers should pay attention to data interoperability: the ability of the data to work with different systems or products. There are some examples of open standard formats which can communicate with different systems:

    Type of Data

    Format of Data

    Images

    PNG and SVG

    Web Pages

    HTML

    Tabular Data

    XML, CSV and JSON

  • Data Cleansing and Data Transformation

    For most cases, data cleansing is a necessary process of detecting and eliminating errors, inconsistencies and duplications from data so as to enhance the quality of a database. After data cleansing, data transformation may be needed to convert data from one format into another. For example, researchers may need to convert KML data (a geo-data format used in Google Map) into JSON format (a geo-data format widely applicable to GIS software such as QGIS) for visualising data on a map.

  • Data Analysis

    Data visualisation techniques are widely applied to statistical analysis, text analysis and geospatial analysis. The advanced data visualisation methods can give researchers new insights.

    Type of Analysis

    Examples of Data Visualisation Tools

    Statistical Analysis

    Graphs and Infographics

    Text Analysis

    Word Cloud, Word Tree, Collocation Graph

    Geospatial analysis

    Map, Network Graph

  • Data Visualisation

    To achieve different goals and functionalities, researchers can use different kinds of data visualisation tools. Some common types of graphs can be found in Data Visualisation Catalogue.
