<h1>Viennas fastest growing areas</h1>

<p> This scatterplot shows the positive correlation of total population change and foreign population change until 2024 in Vienna. However, the chart excludes two outliers, like the area around a new railwaystation, which will be the hotspot of population growth. Data has been gathared by <a href="https://www.data.gv.at/katalog/dataset/7a6156e3-2242-4e4f-8158-2b80ecd89189" style="color:#33aafc">the administration.</a></p>
