A bar chart can be used to compare categorical data. Each bar represents a category which is treated as a variable and whose value is shown on the horizontal axis.
In a bubble chart, each point would be associated with three variables and mapped on a Cartesian grid in order to: (a) show the distribution of data, and (b) permit simple quantitative comparisons.
A column chart can be used to compare categorical data. Each column represents a category which is treated as a variable and whose value is shown on the vertical axis. Grouped columns permit comparisons within a category.
Analytics information resulting from a conversion funnel can be used by designers to (a) improve the customer journey, i.e. from clicking a web banner to closing the sale, and (b) to increase the conversion rate.
A flow chart can be used to visualise processes, computer algorithms, or user navigation structures. This typically involves a number of steps and decisions, shown as boxes, and connecting arrow heads to convey sequence.
A Gantt chart is used for planning and managing projects. This chart displays tasks, durations, and dependencies against a timescale so as to permit progress tracking and target-performance comparisons.
Continuous data with many points, such as time series data, can be visualised using a line chart. It facilitates identifying trends, patterns, and relationships.
Org charts depict the structure of an organisation, including the roles, ranks, and responsibilities of its personnel. Vertical connecting lines represent a reporting relationship; horizontal lines indicate a working relationship.
A pictogram is usually a representational symbol, but in a chart it may also stand for a numerical value. Pictographic representations thus require a key so the reader can associate the symbol with physical objects.
A pie chart conveys the composition of data at a glance by showing the relationship of parts to each other and to a whole. Segments can be expressed, or labelled, as percentages.
A scatter plot indicates the distribution of data, as well as correlations between variables. A Cartesian coordinate system can be used to plot the values of each pair of variables.
A stacked column chart serves the comparison of categorical data, where each column represents a category. The various layers help indicate the composition of data within a single category.
