Here are some examples of bar charts. Each example shows a chart generated by Google Image Charts followed by the equivalent chart generated by QuickChart.
Vertical bar charts
Horizontal bar charts
This visualization is intended for organizational or process charts. GraphViz is a package of open source tools for visualizing connectivity graphs. You can create GraphViz graphs using the DOT language and your choice of layout engines.
In order to specify a layout engine, append a semicolon to
cht and specify one of the following:
dot(default): "hierarchical" or layered drawings of directed graphs.
neato: "spring model" layout. This is a good engine if the graph is not too large (about 100 nodes) and you don't know anything else about it. Neato attempts to minimize a global energy function, which is equivalent to statistical multi-dimensional scaling.
fdp: "spring model" layout similar to neato, but works by reducing forces rather than working with energy.
twopi: Radial layouts in which nodes are placed on concentric circles depending their distance from the root node.
Note that this visualization returns in SVG format by default and auto-sizes itself. To get a PNG image, add
chof=png. To size the PNG image, use
chs=300x200 (width x height).

See documentation for creating a Radial Gauge.
Other types of charts
Compound charts and multi-axis charts should use Chart.js syntax. See the documentation for Mixed Charts.
