Population

This example demonstrates importing a notebook from ObervableHQ and replacing its data with data of our own (the code and data for this example were originally published here).

First we read from a local JSON file into population:

population = FileAttachment("population.json").json()

Then we import from https://observablehq.com/@d3/zoomable-sunburst and specify that we’d like to use population instead of the data built in to the notebook:

import { chart } with { population as data } from "@d3/zoomable-sunburst"

Finally, we display the chart:

chart

title: "Population"

    toc: false

This example demonstrates importing a notebook from ObervableHQ and replacing its data with data of our own (the code and data for this example were originally published  [here](https://github.com/observablehq/examples/tree/main/custom-data)).

First we read from a local JSON file into `population`:

```{ojs}

Then we import from <https://observablehq.com/@d3/zoomable-sunburst> and specify that we'd like to use `population` instead of the data built in to the notebook:

```{ojs}
import { chart } with { population as data } from "@d3/zoomable-sunburst"

Finally, we display the chart:
