- Sankey Flow Show ( webpage) A web-based Sankey diagram tool by Thortec Software in Germany. Straight-forward drawing of diagrams. Many layout options, e.g. Node types, arrow curves, arrow shadow. Diagrams can be stored locally or in cloud drive. Free trial/student account, pro account at 3.99 US$/month.
A new web-based Sankey tool, Sankey Flow Show, is available from German software maker THORTEC Software.It promises 'attractive flow diagrams made in minutes'. And indeed the tool is rich in features and design options: Different node elements, shadow effect for arrows (called ‘connections'), toggle constant/Sankey connections style, and customizable data input are some of the highlights.
Overview
A sankey diagram is a visualization used to depict a flowfrom one set of values to another. The things being connected arecalled nodes and the connections arecalled links. Sankeys are best used when you want to show amany-to-many mapping between two domains (e.g., universities andmajors) or multiple paths through a set of stages (for instance,Google Analytics uses sankeys to show how traffic flows frompages to other pages on your web site).
For the curious, they're named after Captain Sankey, who created adiagramof steam engine efficiency that used arrows having widthsproportional to heat loss.
Note: The sankey chart may be undergoing substantialrevisions in future Google Charts releases.
Sankey diagrams are rendered in the browser using SVG or VML,whichever is appropriate for the user's browser. Google's sankeylayout code is derived from D3's sankey layout code.
Note: Google sankey charts are unavailable in MicrosoftInternet Explorer 8 and earlier versions.
A Simple Example
Suppose you had two categories, A and B, that connect to threeother categories, X, Y, and Z. Some of those connections are heavierthan others. For instance, B has a thin connection to X and a muchthicker connection to Y.
Try hovering over one of the links to highlight the connection.
To create a sankey chart, provide a set of rows, with eachcontaining information about one connection: from, to, andweight. Then use the google.visualization.Sankey()
methodto initialize the chart and then the draw()
method torender it:
Note: Avoid cycles in your data: if A links to itself, orlinks to B which links to C which links to A, your chart will notrender.
Multilevel Sankeys
You can create a Sankey chart with multiple levels of connections:
Sankey charts will add additional levels as needed, laying them outautomatically. Here's the complete code for the above chart:
Controlling Colors
Sankey charts have the ability to set custom colors for nodes and links. Both nodes and links can be given custom color palettes using their colors
options (sankey.node.colors
and sankey.link.colors
, respectively). They can also be given different coloring modes using the colorMode
option.
If the colors aren't customized, they default to the standardMaterial palette.
You can control the colors of the links, nodes, and labels withconfiguration options. Here, we select three with the same hue butdifferent brightnesses:
Here's what those options look like:
You can also control the transparency of the links withthe sankey.link.color.fillOpacity
option:

To create a border around the links, usethe sankey.link.color.stroke
and sankey.link.color.strokeWidth
options:
The stroke color can be specified either in RGB format or byEnglish name.
Customizing Labels
The text on sankey charts can be customizedusing sankey.node.label.fontName
and friends:
Here's the option stanza for the above chart:
You can adjust the position of the labels relative to the nodeswith the sankey.node.labelPadding
option:
In the chart above, we've added 30 pixels of padding between the labelsand the nodes.
Adjusting Nodes
You can control the width of the nodeswith sankey.node.width
:
Above, we set the node width to 2.
You can adjust the distance between the nodeswith sankey.node.nodePadding
:

Data Format
Rows: Each row in the table represents aconnection between two labels. The third column indicates the strengthof that connection, and will be reflected in the width of the pathbetween the labels.
Columns:
Column 0 | Column 1 | Column 2 | .. | Column N (optional) | |
---|---|---|---|---|---|
Purpose: | Source | Destination | Value | .. | Optional roles |
Data Type: | string | string | number | .. | |

forceIFrame | Draws the chart inside an inline frame. (Note that on IE8, this option is ignored; all IE8 charts are drawn in i-frames.) Default: false |
height | Height of the chart, in pixels. Default: height of the containing element |
sankey.iterations | With multilevel sankeys, it's sometimes nonobvious where nodes should be placed for optimal readability. The D3 layout engine experiments with different node layouts, stopping when Default: 32 |
sankey.link | Controls attributes of the connections between nodes. Currently all attributes pertain to color: Default: null |
sankey.link.colorMode | Sets a coloring mode for the links between nodes. Possible values:
This option overrides sankey.link.color. Default: 'none' |
sankey.node | Controls attributes of the nodes (the vertical bars between links): Default: null |

tooltip | An object with members to configure various tooltip elements. To specify properties of this object, you can use object literal notation, as shown here: Default: null |
