This interactive choropleth map displays global data science salaries, using a color scale from dark purple to bright yellow to represent the salary ranges across countries. Users can filter the map's color distribution through two sliders that adjust the minimum and maximum salary values, while hovering over individual countries reveals a tooltip with the country name and its corresponding salary figure. The visualization is built with D3.js, utilizing `d3.geoMercator` for map projection, `d3.geoPath` to render country boundaries, and a `d3.scaleLinear` color scheme, with data sourced from a CSV file and world geometry from a GeoJSON file.
