Space between labels and line in gganimate-CodePudding

I have tried to create an animated graph for which I am using geom_smooth that moves and also the labels that move with the lines. However, I am not able to provide space between the line and labels so their legibility is affected. Need to solve this.

The code for plotting the animation is as follows.

p <- ggplot(tbl66, aes(x=TRDAY, y=log(AVMKTPC), col=LABEL2, group = LABEL2))   geom_line(size=1)   
  theme(legend.position="none")  
  theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))  
  geom_dl(aes(label = LABEL2), method = list(dl.combine("first.points")), cex = 1)   
  theme(panel.background = element_rect(fill = "#030905"))  
  theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank())  
  transition_reveal(TRDAY)   
  ease_aes('cubic-in-out')  
  labs(title = 'Date: {frame_along}')  
  theme(legend.position = 'none',
        title = element_text(size = 11, face = "bold"),
        axis.title.x = element_blank(),
        axis.title = element_text(size = 14, face = "bold"),
        strip.text = element_text(size = 14, face = "bold"),
        plot.caption = element_text(face = "italic"))

animate(p, 10, .2, height=900, width=1100, res=100)
anim_save("codovid.gif")

The sample data is given here. It provides three columns one is the date column and the second is the value column and the third is the label column. I need these values to run ahead of line with some space.

One option would be to use geom_text(aes(label = LABEL2), hjust = -0.1) to left align the labels with the data points and to add some padding:

library(gganimate)
#> Loading required package: ggplot2

p <- ggplot(tbl66, aes(x=TRDAY, y=log(AVMKTPC), col=LABEL2, group = LABEL2))   geom_line(size=1)   
  theme(legend.position="none")  
  theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))  
  geom_text(aes(label = LABEL2), hjust = -0.1)  
  theme(panel.background = element_rect(fill = "#030905"))  
  theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank())  
  transition_reveal(TRDAY)   
  ease_aes('cubic-in-out')  
  labs(title = 'Date: {frame_along}')  
  theme(legend.position = 'none',
        title = element_text(size = 11, face = "bold"),
        axis.title.x = element_blank(),
        axis.title = element_text(size = 14, face = "bold"),
        strip.text = element_text(size = 14, face = "bold"),
        plot.caption = element_text(face = "italic"))
