Correlation matrix
A correlation matrix is done to see where there is a correlation among the data. is a calculated protein correlation matrix for phage T7. Correlated behavior ranges from high(red) to low(blue), and the triangular block of red reflects proteins involved in phage assembly, a highly coordinated process.
Similarity matrix
A similarity matrix is used to show how similar (or not) the variables are to one another. This image is an autocorrelation plot of the similarity matrix generated by the unstabilized weighted scanline buffer. It is very difficult to see any pattern in this matrix.

Population profile
Population profiles present a graphic overview of several demographic statistics collectedusing certain data. They can depict a wide range of variables through different methods. Here is an example of population with age range, sex, and immigration status.
Scatterplot
A scatterplot is a useful summary of a set of bivariate data (two variables), usually drawn before working out a linear correlation coefficient or fitting a regression line. It gives a good visual picture of the relationship between the two variables, and aids the interpretation of the correlation coefficient or regression model. This image shows the differences between a wiffe and husbands' age.

Accumulative line graph or Lorenz curve
The lorenze curve graphically represents the cumulative distribution function of a probability distribution. It is frequently used to display income distribution. This shows the amount of income earned by the poorest 20% of the population.
Bilateral Graph
A bilateral graph depicts increases on one side of a zero line and a decreases on the other side. Bilateral graphs are used to display data when there is both positive and negative values. Here is an example that shows the trends in the amount of interest on a home.

Classed choropleth maps
A classed choropleth map the main objective is to determine height and shading or color intensity of the bar for each map classed. This would involve creating a classed frequency legend including a frequency histogram, a frequency curve, and shading. An example of this is the distribution of males per 100 females.
