This heatmap visualizes Airbnb rental prices across Dallas, using a color gradient to show how nightly costs vary by geographic location. The visualization plots price values against longitude and latitude coordinates, with the chart title and axis labels clarifying the spatial distribution. Built with Plotly's JavaScript API, the code loads data from a local CSV file using `Plotly.d3.csv`, then constructs a single heatmap trace with the `type: 'heatmap'` parameter. The resulting map is rendered into a designated HTML div element using `Plotly.newPlot`.
