Treemap
History of Treemap Ben Shneiderman is considered to be the inventor of Treemaps. He created treemaps as a way to visualize a vast file directory on a computer, without taking up too much space on the screen. Treemap has subsequently become an essential method for displaying hierarchical data using nested figures and rectangles in information […]
Tag Cloud
History of Tag Cloud The earliest printed example of a weighted list of English keywords was the “subconscious files” in Douglas Coupland’s Microserfs in 1995. This popularized tags becoming commonly used on geographic maps to represent the relative size of cities in terms of relative typeface size. The “tag cloud” rose to prominence in the […]
Stacked Bar Chart
Stacked charts are a kind of bar chart which are multiple-series in nature where related values are placed atop one another. This feature allows comparing the contribution of a value to a total, either in absolute or percentage terms along with comparing multiple categories and category totals simultaneously. [chartdesc] History of Stacked Bar Chart Stacked […]
Spider Graph
A Radar Chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The value of each aspect is depicted by the node (anchor) on the spoke (axis) and a line is drawn connecting the data […]
Pie Chart
A pie chart is named for its resemblance to a sliced pie and is a circular visual representation illustrating numerical proportions through slices made in a circle. Here the arc length of each slice is proportional to the quantity it represents(and consequently its central angle and area). There are many variations in the way pie […]
Line Chart
A line chart also known as a line plot or a line graph, is a type of chart that displays information as a series of data points called ‘markers’ connected by straight line segments. Commonly used in different fields to represent correlation between variables it is similar to a scatterplot, except that the measurement points […]
Heatmap
Heat Maps are most commonly used to display a more generalized view of numeric values as a graphical representation of data where the individual values contained in a matrix are represented as colors. It is commonly used as an isopleth representing regions of similar value using color splotches. Heatmaps use color the way a bar […]
Gantt Chart
A Gantt chart visualization shows activities (tasks or events) displayed against time, most commonly used for the purpose of project management and scheduling. On one axis is a list of the activities and along the other is a suitable time scale. Each activity is represented by a bar; where the position and length of the […]
Bubble Chart
A bubble chart represents data points replaced with bubbles, adding an additional dimension of the data represented through the size of the bubbles. As a variation of a scatter chart, a bubble chart similarly does not use a category axis — both horizontal and vertical axes are value axes. [chartdesc] History of Bubble Chart Bubble […]
Circular Barplot
A circular barplot is a plot where each bar is displayed along a circle instead of a line. Here no Y scale is displayed since exact values are written on each bar which could also be represented on interaction with the chart. The chart is popular for its visual appeal however and needs to be […]
