Map bars
CSV map 3D bars
Upload province or city values as CSV and build a rotatable 3D map bar chart.
How to use
Need at least a region name column (Guangdong / 广东 / Shenzhen, or adcode) and a numeric column. Try the samples. Parsing and charting stay in the browser.
China · provinces matches 34 provincial units. One province · cities picks a province then matches its prefecture-level cities. Right-drag to rotate, scroll to zoom.
Is my CSV uploaded?
No. Parsing and ECharts-GL rendering run entirely in your browser.
Do short region names work?
Common short names and six-digit adcodes are supported. Add an adcode column if matching still fails.
Can this replace official maps or statistics?
No. Boundaries are illustrative internet data. The chart is for learning and business demos only.
These tools only assist with geographic data processing. Outputs are for technical reference and must not be used for survey acceptance, construction, or official cadastral demarcation. For critical work, rely on professional GIS software and licensed survey products. All computation runs locally in the browser; files are not uploaded. This site does not operate a public map tile service, does not provide a geography API, does not parse classified coordinates, and does not display militarily sensitive locations. The basemap is OpenStreetMap.
