md` ## Data and Tools
I gathered and filtered the data using the public DataCite API (https://api.datacite.org) in february 2020. Therefore data is limited to research datasets that have a DOI assigned.
The visulisation is made using two separated Vega-lite specifications; one per chart.
`

md`## Live Monitoring
Below there is live monitoring of the datasets with citations`
vegalite = require("@observablehq/vega-lite@0.2")
d3 = require("https://d3js.org/d3.v5.min.js");
data = d3.json("https://api.datacite.org/dois?resource-type-id=dataset&has-citations=1");
citations = data.meta["citations"];
certificates = data.meta["certificates"];
One platform to build and deploy the best data apps
Experiment and prototype by building visualizations in live JavaScript notebooks. Collaborate with your team and decide which concepts to build out.
Use Observable Framework to build data apps locally. Use data loaders to build in any language or library, including Python, SQL, and R.
Seamlessly deploy to Observable. Test before you ship, use automatic deploy-on-commit, and ensure your projects are always up-to-date.
