Improve the model$/$algorithm: I left plenty of room for improvement when I use the Support Vector Machine $($SVM$)$ algorithm in the guided project. Among the performance metrics presented in the guided project, which one do you think makes the most sense? Why? In Orange Data Mining, implement another model$/$algorithm that performances better on the test data; $(20$ points$)$

Improve the visualizations: Provide two additional visualizations. You can be improving on the existed ones, but the improvement needs to be significant: for example, changing labels and$/$or colors do not constitute as a significant improvement; $(10$ points$)$
