# Sankey diagram (v10.3.0+)
|
|
|
|
> A sankey diagram is a visualization used to depict a flow from one set of values to another.
|
|
|
|
> **Warning**
|
|
> This is an experimental diagram. Its syntax are very close to plain CSV, but it is to be extended in the nearest future.

|
|
|
The things being connected are called nodes and the connections are called links.

## Example
|
|
|
|
This example taken from [observable](https://observablehq.com/@d3/sankey/2?collection=@d3/d3-sankey). It may be rendered a little bit differently, though, in terms of size and colors.

## Syntax
|
|
|
|
The idea behind syntax is that a user types `sankey-beta` keyword first, then pastes raw CSV below and get the result.
|
|
|
|
It implements CSV standard as [described here](https://www.ietf.org/rfc/rfc4180.txt) with subtle **differences**:
|
|
|
|
- CSV must contain **3 columns only**
|
|
- It is **allowed** to have **empty lines** without comma separators for visual purposes
|
|
|
|
### Basic
|
|
|
|
It is implied that 3 columns inside CSV should represent `source`, `target` and `value` accordingly:
|
|
|
|
```mermaid-example
|
|
sankey-beta
|
|
|
|
%% source,target,value
|
|
Electricity grid,Over generation / exports,104.453
|
|
Electricity grid,Heating and cooling - homes,113.726
|
|
Electricity grid,H2 conversion,27.14
|
|
```
|
|
|
|
```mermaid
|
|
sankey-beta
|
|
|
|
%% source,target,value
|
|
Electricity grid,Over generation / exports,104.453
|
|
Electricity grid,Heating and cooling - homes,113.726
|
|
Electricity grid,H2 conversion,27.14
|
|
```
|
|
|
|
### Empty Lines
|
|
|
|
CSV does not support empty lines without comma delimiters by default. But you can add them if needed:
|
|
|
|
```mermaid-example
|
|
sankey-beta
|
|
|
|
Bio-conversion,Losses,26.862
|
|
|
|
Bio-conversion,Solid,280.322
|
|
|
|
Bio-conversion,Gas,81.144
|
|
```
|
|
|
|
```mermaid
|
|
sankey-beta
|
|
|
|
Bio-conversion,Losses,26.862
|
|
|
|
Bio-conversion,Solid,280.322
|
|
|
|
Bio-conversion,Gas,81.144
|
|
```
|
|
|
|
### Commas
|
|
|
|
If you need to have a comma, wrap it in double quotes:
|
|
|
|
```mermaid-example
|
|
sankey-beta
|
|
|
|
Pumped heat,"Heating and cooling, homes",193.026
|
|
Pumped heat,"Heating and cooling, commercial",70.672
|
|
```
|
|
|
|
```mermaid
|
|
sankey-beta
|
|
|
|
Pumped heat,"Heating and cooling, homes",193.026
|
|
Pumped heat,"Heating and cooling, commercial",70.672
|
|
```
|
|
|
|
### Double Quotes
|
|
|
|
If you need to have double quote, put a pair of them inside quoted string:
|
|
|
|
```mermaid-example
|
|
sankey-beta
|
|
|
|
Pumped heat,"Heating and cooling, ""homes""",193.026
|
|
Pumped heat,"Heating and cooling, ""commercial""",70.672
|
|
```
|
|
|
|
```mermaid
|
|
sankey-beta
|
|
|
|
Pumped heat,"Heating and cooling, ""homes""",193.026
|
|
Pumped heat,"Heating and cooling, ""commercial""",70.672
|
|
```
|
|
|
|
## Configuration
|
|
|
|
You can customize link colors, node alignments and diagram dimensions.
|
|
|
|
```html
|
|
<script>
|
|
const config = {
|
|
startOnLoad: true,
|
|
securityLevel: 'loose',
|
|
sankey: {
|
|
width: 800,
|
|
height: 400,
|
|
linkColor: 'source',
|
|
nodeAlignment: 'left',
|
|
},
|
|
};
|
|
mermaid.initialize(config);
|
|
</script>
|
|
```
|
|
|
|
### Links Coloring
|
|
|
|
You can adjust links' color by setting `linkColor` to one of those:
|
|
|
|
- `source` - link will be of a source node color
|
|
- `target` - link will be of a target node color
|
|
- `gradient` - link color will be smoothly transient between source and target node colors
|
|
- hex code of color, like `#a1a1a1`
|
|
|
|
### Node Alignment
|
|
|
|
Graph layout can be changed by setting `nodeAlignment` to:
|
|
|
|
- `justify`
|
|
- `center`
|
|
- `left`
|
|
- `right`
|
