This example shows a pie chart displaying the distribution of parking area start years from RDW open data, where each slice represents a unique year value from the dataset. The visualization fetches JSON data from the RDW API, filters it to extract the first four characters of the `startdataarea` column, and identifies unique values before rendering the chart. Using D3 v6, the code employs `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with the `schemeTableau10` color palette to generate SVG paths and labels. Text labels are placed using an inner arc centroid calculation.

Pie chart RDW With help from Laurens

This example shows a pie chart of parking data from the RDW open data API, visualizing the distribution of start dates by year. The code loads JSON data via `fetch`, filters it to the first four characters of the `startdataarea` field, counts occurrences per year, and renders the chart using D3.js v6’s `d3.pie`, `d3.arc`, and `d3.scaleOrdinal`. The SVG is centered on the page, with each slice labeled by year and colored using the category10 scheme.

Pie chart RDW beter?

This visualization displays a pie chart that uses data from the RDW (Dutch vehicle registration authority) to explore parking usage purposes, though the chart currently renders hardcoded year values (2013–2019) rather than the fetched API data. The code fetches JSON from two RDW Open Data endpoints using the Fetch API, filters location data by the `startdataarea` column, and then builds the chart with d3.pie() and d3.arc(), styled with d3.scaleOrdinal and d3.schemeCategory10. Rendering occurs as SVG elements within a 400x400 viewport.

Pie chart RDW Final 2 datasets

This example presents a donut pie chart displaying parking data from two Dutch RDW datasets, showing the distribution of years extracted from start and end area values. The visualization includes interactive hover effects and click events on arc segments. Built with D3.js v6, the code uses d3.pie, d3.arc, and d3.scaleOrdinal to generate the SVG chart, with buttons to switch between datasets. Data is loaded asynchronously from the RDW Open Data API via fetch and processed through custom filtering functions that slice four-digit year values from the selected columns.

Pie chart RDW filter op andere dataset

This example visualizes the distribution of parking data usage years from the RDW open dataset, filtering by the `usageid` and `startdataarea` columns, and aggregating counts per year into a pie chart. It fetches data from the RDW API via `fetch`, filters and maps values with custom functions, then uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with `d3.schemeCategory10` to render the SVG slices. Labels are placed using `arc.centroid`, and the chart displays unique year values as text on each segment. The dataset is retrieved from `opendata.rdw.nl` with a CORS proxy.

Pie chart RDW Final

This pie chart displays how many Park & Ride locations were created per year, based on Dutch open data from RDW. The chart uses d3.pie and d3.arc to generate slices, with each slice labeled by year and count, colored via d3.scaleOrdinal. Hovering a slice triggers a transition that expands the arc using d3.arc with adjusted radii. The data is fetched from two RDW JSON endpoints using async/await, filtered and aggregated before rendering as an SVG.

Pie chart RDW

This example displays a pie chart of yearly values using D3.js, rendering four labeled slices with a categorical color scheme. The visualization is built with the `d3.pie` layout function and `d3.arc` for paths and labels, rendered as SVG. It uses `d3.scaleOrdinal` for colors and `d3.schemeCategory10` for the palette, with data hardcoded in the script. The chart is centered using an SVG group transform, and each slice’s year is placed via the label centroid.

Fork of Pie chart RDW

This D3.js (v6) example renders a simple pie chart using SVG, displaying four data points that map years (2013, 2014, 2015, 2019) to numeric values. The chart uses `d3.pie()` to compute arc segments and `d3.arc().outerRadius(200)` to define the pie geometry, with each slice filled by a category-10 color based on its value. Year labels are placed using the `centroid()` method of an inner arc, offset from the center. The data is hardcoded in the script, and the visualization is centered on a 400×400 SVG canvas using CSS transforms.

Fork of Pie chart RDW

This example shows a simple pie chart of four data points representing yearly values from 2013 to 2019. Each slice is labeled with its corresponding year, and the chart uses a categorical color scheme to differentiate the segments. The visualization is built using D3 v6, with `d3.pie()` computing the arc angles, `d3.arc()` generating the SVG path shapes, and the `centroid` method positioning the year labels at the center of each slice. The data is hardcoded in the script, and the SVG is centered on the page via CSS.
