Highlighting a specific data point in line chart

Hello Gurus,

I have a line graph with 2 lines that plots the Actuals vs Planned values for a metric. On the X-axis I have the month-year. I have a requirement where I need to add some sort of a differentiator/ highlighting for the "current month" data point. Is this something that is possible? 

I have attached my graph below. As you can see the last data point that corresponds to Jan 2021. I need some sort of visual distingusing feature to make this one data point stand out (maybe the marker has a different color or a pop up when user hovers over it). Not sure if there is a standard way of doing it
