Schema.org – How to present Statistical data in markup

I have a website where I visualize statistical data with geoJSON. The description of a statistic e.g. is Graduation ratio of primary education and the data looks smth. like:

features: [ {     geometry: {type: "Polygon", coordinates: Array(1)}     properties: {name: "Afghanistan", id: "AF", value: 64, latitude: 33, longitude: 65, …}     type: "Feature" }, {     geometry: {type: "Polygon", coordinates: Array(1)}     properties: {name: "Albania", id: "AL", value: 98, latitude: 41, longitude: 20, …}     type: "Feature" } ] 

My question is now on how could I represent this data best with schema.org. There are 2 types which I feel like could come close to it:

  • https://schema.org/Observation
  • https://schema.org/Dataset

I went with the dataSet approach and the markup looks to smth like this:

@context: "http://schema.org" @type: "Dataset" creator: {@type: "Organization", url: "...", name: "Eduinsights", contactPoint: {…}} description: "Global visualization for educational statistics/observations provided by UNESCO: Graduation ratio of primary education,Net enrolment rate for primary education,Percentage of female repeaters primary education,Percentage of qualified teachers secondary education,Proportion of primary schools with access to internet for pedagogical purposes" keywords: ["Statistics > education > Graduation ratio of primary education", "Statistics > education > Net enrolment rate for primary education", "Statistics > education > Percentage of female repeaters primary education", "Statistics > education > Percentage of qualified teachers secondary education", "Statistics > education > Proportion of primary sch… with access to internet for pedagogical purposes"] name: "Educational statistics" spatialCoverage: {@type: "Place", geo: {…}} temporalCoverage: "Thu Jan 01 1970 01:00:02 GMT+0100 (Mitteleuropäische Normalzeit)/Thu Jan 01 1970 01:00:02 GMT+0100 (Mitteleuropäische Normalzeit)" url: "..." 

Is this really the right way to go? There are not much sources online about schema.org representation of statistical data.
