Hi, I am currently using the v6.2.0 Charts package to create some dashboards. I want to create a custom chart which is going to be a Choropleth Map. The issue is that once I generate the JSON values (using this guide) of "locations" and "z" for the map, the Mendix runtime throws an exception of "Failed to parse data for trace(0)".   This is my Static Data [{ "type": "choropleth", "geojson": "https://raw.githubusercontent.com/datasets/geo-countries/main/data/countries.geojson", "locationmode": "country names", "colorscale": [ [0, "#00d7a0"], [1, "#00bedc"] ], "autocolorscale": false, "reversescale": true, "colorbar": { "autotic": false, "title": {"text": "Count"} } }] This is my Sample Data (which also does not work) [{ "locations": [ "Brazil", "Belgium", "Australia", "India", "United States" ], "z": [1, 2, 3, 10, 6] }]   The funny part is that if I plug in this exact Sample Data JSON to the trace0 in Chart Playground it works like a charm, not sure what I am doing here that is causing this to fail.   Any help in this matter is highly appreciated!   EDIT -- 27 Jun 2025   After some debugging I have found out that the static and sample data windows are not working as intended. If you have any static data it completely overrides the sample data or the source attribute thus causing issues when rendering the chart. I still have not figured out the issue for parsing of the JSON.
