The Density 2D plot
History of Density 2D A density plot is a smoothed, continuous version of a histogram estimated from the data. The most common form of estimation is based out of kernel density estimation (KDE). In this method, a continuous curve (the kernel) is drawn at every individual data point and all of these curves are then […]
Scatterplot
A scatter plot, also known as a scatter chart or a scatter graph, is a two-dimensional data visualization that uses dots to represent the values obtained for two different variables – one plotted along the x-axis and the other plotted along the y-axis. Scatter plots are primarily used to indicate the relationship between two variables […]
Histogram
A histogram graph is a plot that lets one represent data points that lie in a range of values called classes or bins creating a frequency distribution of a continuous set of data. This allows for the inspection of the data for its underlying distribution (e.g. normal distribution), outliers, skewness, etc. Being one of the […]
Hexbin
Hexbin map uses hexagons to split the area into several parts and attribute a color to it. The graphic area (which can be a geographical area) is divided into a multitude of hexagons and the number of data points in each is counted and represented using a color gradient. This chart is used to visualize […]
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 […]
Choropleth
A choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. Choropleth maps provide an easy way to visualize how a measurement varies across a geographic area or show the level […]
