- **Topic Evolution Heatmap**:
The intensity of cells reflects the prominence of each topic during specific time slices, enabling a clear visualization of how topics evolve over time. This highlights shifts in focus and reveals time-dependent changes. By examining the keywords associated with each topic, we can contextualize its theme and track how it responds to external factors, such as events or trends.

### 3. **Correlation with Polls, Google Trends and Sentiment**
Add tables of metrics/technique results calculates and plots.
Every possible combination of polling data or search interest with sentiment was analyzed:
- **Trump-Biden Period**:
- Polls (Trump) with sentiment for Trump and Biden individually, and combined.
- Polls (Biden) with sentiment for Trump, Biden, and their combination.
- **Trump-Harris Period**:
- Polls (Trump) with sentiment for Trump and Harris individually, and combined.
- Polls (Harris) with sentiment for Trump, Harris, and their combination.
- The same combinations were repeated for Google search interest data.
Every possible combination of polling data or search interest with support score was analyzed:
- **Sentiment as exogenous variable for polls**:
- Trump polls on Biden period:
- Trump love as exogenous coefficient: **0.0179**
- Biden love as exogenous coefficient: **-0.0008**
- Biden and Trump love as exogenous coefficients: **-0.0009**, **0.0174**

- Trump polls on Harris period:
- Trump love as exogenous coefficient: **0.0017**
- Harris love as exogenous coefficient: **-0.0006**
- Harris and Trump love as exogenous coefficients: **-0.0005**, **0.0017**
- Harris polls:
- Trump love as exogenous coefficient: **-0.0052**
- Harris love as exogenous coefficient: **0.0011**
- Harris and Trump love as exogenous coefficients: **0.0013**, **-0.0059**
- **Setiment as exogenous variable for google searches**:
- Trump google searches on Biden period:
- Trump love as exogenous coefficient: **-0.7114**
