Hierarchy

A template for grouping data and visualising it hierarchically

Updated 2 months ago to v16.0.1 by Flourish team

How to use this template

This template is great for summarising your data across different categories.

Your data is summarised (like a pivot table) then visualised using one of five chart types:

  • Treemap (nested rectangles)
  • Circles (nested circles)
  • Sunburst (layered circular segments)
  • Bar (stacked bar chart)
  • Radial (radial bar chart)

Hierarchy chart types

As an example, suppose you have the following sales data:

Type Colour Price
T-shirt Red 10
T-shirt Yellow 15
T-shirt Red 10
Jeans Blue 30
Jeans Blue 35

You choose:

  • one or more columns to summarise by (using the "Nesting" binding) and
  • a column to size by (using the "Size by" binding).

For example if you set the "Nesting" binding to Type and the "Size by" binding to Price the data is summarised as:

Type Price
T-shirt 35
Jeans 65

(Notice that Price is summed for each Type.)

If Treemap is chosen you'll see:

Treemap

and if Sunburst is chosen you'll see:

Circles

If the "Nesting" binding is changed to Type and Colour the data is summarised as:

Type Colour Price
T-shirt Red 20
T-shirt Yellow 15
Jeans Blue 65

(Price is summed for each combination of Type and Colour.)

If Treemap is chosen you'll see that each Type (T-shirt, Jeans etc.) contains rectangles for each Colour (Red, Yellow, Blue etc.):

Treemap

If Sunburst is chosen you'll see that each Type (T-shirt, Jeans etc.) divides into segments for each Colour (Red, Yellow, Blue etc.):

Circles

Each column in the "Nesting" binding forms a layer in a hierarchy. In the above example the first layer represents Type (T-shirt or Jeans) and the second layer represents Colour (Red, Yellow or Blue).

Data requirements

The data should be in "long-form" i.e. each row represents a single data-point and each column represents a variable. For example:

Film Genre Studio Worldwide Gross
27 Dresses Comedy Fox 160.31
(500) Days of Summer Comedy Fox 60.72
A Dangerous Method Drama Independent 8.97
A Serious Man Drama Universal 30.68
Across the Universe Romance Independent 29.37
Beginners Comedy Independent 14.31
Dear John Drama Sony 114.97

Data bindings

Columns are either categorical (e.g. Genre and Studio) or numeric (e.g. Worldwide Gross).

Choose:

  • categorical columns for the "Nesting" binding
  • a numeric column for the "Size by" binding

For example, if you wanted to know which studio took the most revenue set the "Nesting" binding to Studio and the "Size by" binding to Worldwide Gross.

If you wanted to break down each studio by genre set the "Nesting" binding to Studio and Genre.

Zooming

If two or more "Nesting" columns are chosen you'll be able to zoom into a category by clicking. Zoom out by clicking the triangle that appears in the top right of the chart.

Custom popups

Custom popup content may be defined for items at the deepest level in the hierarchy.

Enable by selecting "Custom content" in the Popups menu. In the custom popup template you can use columns from the "Nesting" and "Size by" bindings. You can also add other columns by using the "Info for popups" binding.

Custom popups only work when the hovered item represents a single row of data.

See this tutorial for more detailed information.

Tips

  • You don't have to choose a column to size by. If you do not, the shapes will be sized by the count of data points.
  • Click on the popup to freeze it. Click on it again to unfreeze.
  • You can choose the number of visible hierarchy levels. Try varying this within a story to gradually break down categories into sub-categories.
  • You can also add a filter menu. To do this, set the "Filter" column setting in the data area.

This section documents API usage specific to this template, so for an introduction we suggest you refer to the generic API documentation instead.

template: @flourish/hierarchy

version: 16

Template data

There are two different formats in which you can supply data to this template. Which one will be more convenient for you likely depends on the source of your data, as described below.

Array of objects with arbitrary keys, and a bindings object

This format is most likely useful when you have data from an external source, such as CSV data loaded from d3-dsv. You should supply this attached to the opts.data, which might look like:

    {
        data: [
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            ...
        ]
    }

... but with the keys being the column headers from your source data instead. To tell the API how these values from each column should be associated with the keys that the template is expecting, you must also supply an object attached to opts.bindings. (The meanings of the keys in the bindings object are documented below.) The minimal bindings you can supply for this template are as shown in this example:

{
    template: "@flourish/hierarchy",
    version: "16",
    bindings: {
        data: {
            
        }
    },
    data: {
        data: [
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            ...
        ]
    }
}

All possible bindings that you can supply are shown in this example:

{
    template: "@flourish/hierarchy",
    version: "16",
    bindings: {
        data: {
            nest_columns: ["DataHeader1", "DataHeader2", ...],
            size_columns: ["DataHeader3", "DataHeader4", ...],
            filter: "DataHeader5",
            popup_metadata: ["DataHeader6", "DataHeader7", ...]
        }
    },
    data: {
        data: [
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            { "DataHeader1": ..., "DataHeader2": ..., ... },
            ...
        ]
    }
}

(As before, the keys containing "Header" would be replaced by column names from your data source.)

Array of objects with template-defined keys

There is an alternative format you can use, which is likely to be easier to use if your data is not from a spreadsheet source. With this alternative format you supply your data to the template as an array of objects, attached to opts.data, where the keys must be those used by the template, as documented below. In this case there is no need to supply a bindings object, since the key names are already those expected by the template. The required properties in the data object are as follows (scroll down for a description of what each property is):

{
template: "@flourish/hierarchy",
version: "16",
data: {
    data: [
        {
            nest_columns: [...],
            size_columns: [...],
            popup_metadata: [...]
        },
        ...
    ]
},
...
}

And the full list of all possible properties is as follows:

{
template: "@flourish/hierarchy",
version: "16",
data: {
    data: [
        {
            nest_columns: [...],
            size_columns: [...],
            filter: ...,
            popup_metadata: [...]
        },
        ...
    ]
},
...
}

Meanings of the template data keys:

  • data.nest_columns: Choose one or more categorical columns to ”nest” by. The data is nested in the same order as the chosen columns (e.g. 'C,B' is different from 'B,C')
  • data.size_columns: Optionally choose one or more numeric columns to size by. If more than one is chosen, a dropdown will appear in the visualization which lets the user choose. Rows with negative values are excluded.
  • data.filter: Optionally choose a categorical column to filter by. A dropdown will appear in the visualization.
  • data.popup_metadata: Makes additional columns (text, emoji, image URLs, etc) available in custom popups
