This word cloud visualization displays the frequency of terms related to physics, with larger words like "physics," "matter," and "energy" appearing more prominently. The visualization uses D3.js v4 with the d3.layout.cloud library to position words in a dense, rotated layout. Data from a JavaScript array supplies the text and size values, which are rendered as SVG text elements. The layout algorithm calculates word positions to fill the 560x400 canvas without overlapping.
