Tutorials, guides, and examples for all of the major ones and some others.
The flow chart type is useful for showing changes over time across categories. The geometry is similar to a stacked area chart but with spacing and order changes.
The space between the data and the baseline is filled with a color or a pattern, usually emphasizing counts or percentages for a single variable.
The old standby. The classic. The bar height or length represents data. The baseline starts at zero.
A compact way to show a distribution, line segments represent individual points along a single axis.
It's like a line chart, but it specifically uses a reference point, which becomes the baseline, to compare all the other categories to.
It emphasizes individual points in a distribution instead of binning them like a histogram.
Points are placed like in a scatter plot, but they are sized based on the square root of data values.
It looks like a line chart. However, the focus is specifically on ranks, usually over time.
Regions are colored by a variable. Be careful with your color choices, as they can quickly change what the map shows.
Connected Scatter Plot
A cross between a scatterplot and a time series. Show two variables over time.
It is like a pie chart. But with a hole. It looks like a donut. That's why it's called a donut chart.
Dot Density Map
Dots are placed randomly within regions to show the density of populations. The dots and spacing allow for multiple groups to be shown at once.
Area or line chart value axes overlap to fit more in a space and add another visual aspect to the magnitude of peaks. Also known as: ridgeline chart, joyplot.
It's a type of bar chart that shows the end and start times. The bars are offset by the former.
Cells or bins are colored based on data. As with all visualization types that use color as the main visual encoding, choose shades carefully.
It looks like a bar chart, but it reads differently. The baseline is continuous instead of discrete categories, which allows one to see distributions.
Compact the area chart by slicing it horizontally, and then then shifting the slices to baseline zero. It's like a combo area chart and heatmap.
Also known as a Marimekko diagram, this chart uses the width and height of rectangles to represent separate variables. It can be useful to represent multidimensional data.
Making use of a force-directed graph, bubbles move between different clusters to show grouping over time.
It's also known as an org chart, but I'm going with this from now on because it sounds more sophisticated.
Packed Bubble Chart
Circle size represents data like with a bubble chart, but there is typically no x-y axis. Instead position often represents grouping or is used to maximize space.
Differing scales run alongside each other, sometimes showing relationships between multiple variables through connections. Can be tricky though.
It's everyone's very favorite chart type. It's okay, you can admit it. The slices represent parts of a whole.
Typically used to show the age distributions for population of male and females. Often animated.
Dots are placed in an x-y coordinate system, based on two variables. The plot is often used when it is thought that the variables are correlated.
A specialized line chart, this chart type highlights the change in rank or metric over two time periods.
Square Pie Chart
Instead of using angle to represent parts of a whole, the square version uses, well, squares.
Stacked Area Chart
Place multiple categories on top of each other for a sense of distribution and overall change. Watch out for large counts eclipsing the small ones.
It works like a line chart, but the values change immediately at the x-coordinate instead of with a slope.
Dots are placed along a single continuous scale to show distribution along the corresponding variable.
Show three metrics that sum to a whole. It's good for showing the ratio between the metrics.
Variable Width Bar Chart
The vertical height is the same as a regular bar chart. The widths of bars show another dimension for each category. The two dimensions multiplied, area, should mean something.
